NACCO INDUSTRIES, INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 2022
(In thousands, except as noted and per share amounts)
NOTE 1—Nature of Operations and Basis of Presentation
The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of NACCO Industries, Inc.® (“NACCO”) and its wholly owned subsidiaries (collectively, the “Company”). NACCO brings natural resources to life by delivering aggregates, minerals, reliable fuels and environmental solutions through its robust portfolio of NACCO Natural Resources businesses. The Company operates under three business segments: Coal Mining, North American Mining ("NAMining") and Minerals Management. The Coal Mining segment operates surface coal mines for power generation companies. The NAMining segment is a trusted mining partner for producers of aggregates, coal, lithium and other industrial minerals. The Minerals Management segment, which includes the Catapult Mineral Partners business, acquires and promotes the development of mineral interests. Mitigation Resources of North America® ("Mitigation Resources") provides stream and wetland mitigation solutions.
The Company also has items not directly attributable to a reportable segment. Intercompany accounts and transactions are eliminated in consolidation.
Effective January 1, 2022, the Company changed the composition of its reportable segments. As a result, the Company retrospectively changed its computation of segment operating profit to reclassify the results of Caddo Creek Resources Company, LLC (“Caddo Creek”) and Demery Resources Company, LLC ("Demery") from the Coal Mining segment into the NAMining segment as these operations provide mining solutions for producers of industrial minerals, rather than for power generation. The Coal Mining segment now includes only mines that deliver coal for power generation. This segment reporting change has no impact on consolidated operating results. All prior period segment information has been reclassified to conform to the new presentation. See Note 8 to the Unaudited Condensed Consolidated Financial Statements for further discussion of segment reporting.
The Company’s operating segments are further described below:
Coal Mining Segment
The Coal Mining segment, operating as The North American Coal Corporation® ("NACoal"), operates surface coal mines under long-term contracts with power generation companies pursuant to a service-based business model. Lignite coal is surface mined in North Dakota, Texas and Mississippi. Each mine is fully integrated with its customer's operations and is the exclusive supplier of coal to its customers' facilities.
During the three and six months ended June 30, 2022, the 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”), Mississippi Lignite Mining Company (“MLMC”) and The Sabine Mining Company (“Sabine”). Each of these mines deliver their coal production to adjacent power plants or synfuels plants under long-term supply contracts. MLMC’s coal supply contract contains a take or pay provision; all other coal supply contracts are requirements contracts under which earnings can fluctuate. Certain coal supply contracts can be terminated early, which would result in a reduction to future earnings.
On May 2, 2022, Great River Energy (“GRE”) completed the sale of Coal Creek Station and the adjacent high-voltage direct current transmission line to Rainbow Energy Center, LLC (“Rainbow Energy”) and its affiliates. As a result of the completion of the sale of Coal Creek Station, the existing Coal Sales Agreement, the existing Mortgage and Security Agreement and the existing Option Agreement between GRE and Falkirk were terminated. The Company recognized a gain of $30.9 million within the accompanying Unaudited Condensed Consolidated Statements of Operations during the second quarter of 2022 as GRE paid NACoal $14.0 million in cash, as well as transferred ownership of an office building with an estimated fair value of $4.1 million, and conveyed membership units in a privately-held company involved in the ethanol industry with an estimated fair value of $12.8 million, as agreed to under the termination and release of claims agreement between Falkirk and GRE. Prior to receiving the membership units from GRE, the Company held a $5.0 million investment in the same privately-held company carried at cost, less impairment. Subsequent to the receipt of the additional membership units on May 2, 2022, the Company will prospectively account for the investment under the equity method of accounting. Due to a lag in financial reporting of the privately-held company, the Company has not recorded its share of earnings or losses in the three or six months ended June 30, 2022. On a go-forward basis, earnings or losses from this investment will be recorded on a one quarter lag. See Note 5 for further discussion on fair value.

Table of Contents
The new Coal Sales Agreement (“CSA”) between Falkirk and Rainbow Energy became effective upon the closing of the transaction. Falkirk will continue to supply all coal requirements of Coal Creek Station. Falkirk will be paid a management fee and Rainbow Energy will be responsible for funding all mine operating costs, including mine reclamation, and directly or indirectly providing all of the capital required to operate the mine. The initial production period is expected to run ten years from the effective date of the CSA, but the CSA may be extended or terminated early under certain circumstances. To support the transfer to new ownership, Falkirk has agreed to a reduction in the current per ton management fee from the effective date of the new CSA through May 31, 2024. After May 31, 2024, the per ton management fee increases to a higher base in line with 2021 fee levels, and thereafter adjusts annually according to an index which tracks broad measures of U.S. inflation.
During the three and six months ended June 30, 2021, the Coal Mining segment's operating coal mines also included Bisti Fuels Company, LLC (“Bisti”). Effective September 30, 2021, the contract mining agreement between Bisti and its customer, Navajo Transitional Energy Company ("NTEC"), was terminated.
Coteau operates the Freedom Mine in North Dakota. All coal production from the Freedom Mine is delivered to Basin Electric Power Cooperative (“Basin Electric”). Basin Electric utilizes the coal at the Great Plains Synfuels Plant (the “Synfuels Plant”), Antelope Valley Station and Leland Olds Station. The Synfuels Plant is a coal gasification plant, owned by Dakota Gasification Company (“Dakota Gas’), a subsidiary of Basin Electric, that manufactures synthetic natural gas and produces fertilizers, solvents, phenol, carbon dioxide, and other chemical products for sale. During 2020, Basin Electric informed Coteau that it is considering changes that may result in modifications to its Synfuels Plant that could potentially reduce or eliminate coal requirements at the Synfuels Plant. During 2021, Bakken Energy (“Bakken”) and Basin Electric signed a non-binding term sheet to transfer ownership of the assets of Dakota Gas to Bakken. Bakken stated the closing date is expected to be April 1, 2023. The closing is subject to the satisfaction of specified conditions. As part of the term sheet between Basin Electric and Bakken, Basin Electric indicated that the Synfuels Plant will continue existing operations through 2026. Basin Electric is also considering other options for the Synfuels Plant if the transaction with Bakken does not close.
Sabine operates the Sabine Mine in Texas. All production from Sabine is delivered to Southwestern Electric Power Company's (“SWEPCO”) Henry W. Pirkey Plant (the “Pirkey Plant”). SWEPCO is an American Electric Power (“AEP”) company. AEP intends to retire the Pirkey Plant in 2023. Sabine expects deliveries to cease during the first quarter of 2023 at which time it expects to begin final reclamation. Funding for mine reclamation is the responsibility of SWEPCO.
At Coteau, Coyote Creek, Falkirk and Sabine, the Company is 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 costs, including final mine reclamation, and directly or indirectly provide all of the capital required to build and operate the mine. This contract structure eliminates exposure to spot coal market price fluctuations while providing 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 NACCO and NACoal. See Note 6 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, NACCO does not consolidate the results of these operations within its financial statements. Instead, these contracts are accounted for as equity method investments. The income before income taxes associated with these VIEs is reported as Earnings of unconsolidated operations on the Unaudited Condensed Consolidated Statements of Operations and the Company’s investment is reported on the line Investments in unconsolidated subsidiaries in the Unaudited Condensed 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 the NACCO consolidated U.S. tax return; therefore, the Income tax provision line on the Unaudited Condensed Consolidated Statements of Operations includes income taxes related to these entities. See Note 6 for further information on the Unconsolidated Subsidiaries.
While Falkirk meets the definition of a VIE, the completion of the Rainbow Energy transaction resulted in a VIE reconsideration event. As the terms of the contract between Falkirk and Rainbow Energy are substantially the same as the terms of the contract between Falkirk and GRE, Falkirk will remain a VIE and Rainbow Energy is the primary beneficiary; therefore, NACCO will continue to account for Falkirk under the equity method.
The Company performs 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.

Table of Contents
The MLMC contract is the only operating coal contract in which the Company is responsible for all operating costs, capital requirements and final mine reclamation; therefore, MLMC is consolidated within NACCO’s 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. As diesel fuel is heavily weighted among the indices used to determine the coal sales price, fluctuations in diesel fuel prices can result in significant fluctuations in earnings at MLMC.
MLMC delivers coal to the Red Hills Power Plant in Ackerman, Mississippi. The Red Hills Power Plant supplies electricity to the Tennessee Valley Authority ("TVA") under a long-term Power Purchase Agreement. MLMC’s contract with its customer runs through 2032. TVA’s power portfolio includes coal, nuclear, hydroelectric, natural gas and renewables. The decision of which power plants to dispatch is determined by TVA. Reduction in dispatch of the Red Hills Power Plant will result in reduced earnings at MLMC.
NAMining Segment
The NAMining segment provides value-added contract mining and other services for producers of industrial minerals. The segment is a primary platform for the Company’s growth and diversification of mining activities outside of the thermal coal industry. NAMining provides contract mining services for independently owned mines and quarries, creating value for its customers by performing the mining aspects of its customers’ operations. This allows customers to focus on their areas of expertise: materials handling and processing, product sales and distribution. NAMining historically operated primarily at limestone quarries in Florida, but is focused on continuing to expand outside of Florida, mining materials other than limestone and expanding the scope of mining operations provided to its customers.
NAMining utilizes both fixed price and management fee contract structures. Certain of the entities within the NAMining segment are VIEs and are accounted for under the equity method as Unconsolidated Subsidiaries. See Note 6 for further discussion.
Minerals Management Segment
The Minerals Management segment derives income primarily by leasing its 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.
During 2021 and 2020, the Minerals Management segment acquired mineral interests, primarily in the Eagle Ford and Permian Basins in Texas. During the first six months of 2022, the Minerals Management segment had capital expenditures of $1.0 million, primarily for mineral interests in the New Mexico portion of the Permian Basin. The Minerals Management segment intends to make future acquisitions of mineral and royalty interests that meet the Company’s acquisition criteria as part of its growth strategy.
The Company’s legacy royalty and mineral interests are 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 the Company’s legacy reserves were acquired as part of its historical coal mining operations.
The Minerals Management segment owns royalty interests, mineral interests, nonparticipating royalty interests, and overriding royalty interests. The Company may own more than one type of mineral and royalty interest in the same tract of land. For example, where the Company owns an overriding royalty interest in a lease on the same tract of land in which it owns a mineral interest, the overriding royalty interest in that tract will relate to the same gross acres as the mineral interest in that tract.
The Minerals Management segment will benefit from the continued development of its mineral properties without the need for investment of additional capital once mineral and royalty interests have been acquired. The Minerals Management segment does not have any investments under which it would be required to bear the cost of exploration, production or development.
As an owner of royalty and mineral interests, the Company’s access to information concerning activity and operations of its royalty and mineral interests is limited. The Company does 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.

Certain amounts in the prior period Unaudited Condensed Consolidated Financial Statements have been reclassified to conform to the current period's presentation.
NOTE 2—Revenue Recognition
Nature of Performance Obligations
At contract inception, the Company assesses the goods and services promised in its contracts with customers and identifies a performance obligation for each promised good or service that is distinct. To identify the performance obligations, the Company considers 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 has a contract with its respective customer that represents a contract under ASC 606. For its consolidated entities, the Company’s 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.
At NAMining, the management service is primarily 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.
Included within NAMining, Caddo Creek has a fixed-price contract to perform mine reclamation. The management service to perform mine reclamation 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. Revenue from this contract is recognized over time utilizing the cost-to-cost method to measure the extent of progress toward completion of the performance obligation. The Company believes the cost-to-cost method is the most appropriate method to measure progress and that the rate at which costs are incurred to fulfill the contract best depicts the transfer of control to the customer. The extent of progress towards completion is measured based on the ratio of costs incurred to date compared to total estimated costs at completion, and revenue is recorded proportionally based on an estimated profit margin.
The Minerals Management segment enters into contracts which grant third-party lessees the right to explore, develop, produce and sell minerals controlled by the Company. 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 the Company at the expiration of the contract.
Under these contracts, granting exclusive right, title, and interest in and to minerals 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
10

Table of Contents
component in the form of an up-front lease bonus payment. As the amount of consideration the Company will ultimately be entitled to is entirely susceptible to factors outside its control, the entire amount of variable consideration is constrained at contract inception. The Company believes that the provisions of royalty contracts are customary in the industry. Up-front lease bonus payments represent the fixed portion of the transaction price and are recognized over the primary term of the contract, which is generally five years.
Significant Judgments
The Company’s contracts with its customers 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 the Company's 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, the Company allocates 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.
Recognition of revenue and recognition of profit related to the Caddo Creek contract requires the use of assumptions and estimates related to the total contract value, the total cost at completion, and the measurement of progress towards completion of the performance obligation. Due to the nature of the contract, developing the estimated total contract value and total cost at completion requires the use of significant judgment. The total contract value includes variable consideration. The Company includes variable consideration in the transaction price at the most likely amount to be earned, based upon the Company’s assessment of expected performance. The Company records these amounts only to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved.
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 the Company’s 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. The Company is considered a principal in such transactions and records the associated revenue at the gross amount billed to the customer with the related costs recorded as an expense within cost of sales.
Prior Period Performance Obligations
The Company records royalty income in the month production is delivered to the purchaser. As a non-operator, the Company has limited visibility into when new wells start producing and production statements may not be received for 30 to 90 days or more after the date production is delivered. As a result, the Company is required to estimate the amount of production delivered to the purchaser of the product and the price that will be received for the sale of the product. The expected sales volumes and prices for these properties are estimated and recorded in "Trade accounts receivable" in the accompanying Unaudited Condensed Consolidated Balance Sheets. The difference between the Company’s estimates and the actual amounts received is recorded in the month that payment is received from the third-party lessee. For the three months ended June 30, 2022, royalty income recognized in the reporting periods related to performance obligations satisfied in prior reporting periods was immaterial. For the six months ended June 30, 2022, royalty income of $2.1 million was recognized for a settlement related to the Company’s ownership interest in certain mineral rights. For the three and six months ended June 30, 2021, royalty income recognized in the reporting periods related to performance obligations satisfied in prior reporting periods was immaterial.
Disaggregation of Revenue
In accordance with ASC 606-10-50, the Company disaggregates revenue from contracts with customers into major goods and service lines and timing of transfer of goods and services. The Company 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. The Company’s business consists of the Coal Mining, NAMining and Minerals Management segments as well as Unallocated Items. See Note 8 to the Unaudited Condensed Consolidated Financial Statements for further discussion of segment reporting.

As described above, the Company enters into royalty contracts that grant exclusive right, title, and interest in and to minerals. 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. The timing of the payment of the fixed portion of the transaction price is upfront, however, the performance obligation is satisfied over the primary term of the contract, which is generally five years. Therefore, at the time any such up-front payment is received, a contract liability is recorded which represents deferred revenue. The amount of royalty revenue recognized in both of the three months ended June 30, 2022 and 2021 that was included in the opening contract liability was $0.3 million. The amount of royalty revenue recognized in both of the six months ended June 30, 2022 and 2021 that was included in the opening contract liability was $0.5 million. This revenue consists of up-front lease bonus payments received under royalty contracts that are recognized over the primary term of the royalty contracts, which are generally five years.
The Company expects to recognize an additional $1.6 million in the remainder of 2022, $1.3 million in 2023, $0.1 million in 2024, and de minimis amounts in 2025 and 2026 related to the contract liability remaining at June 30, 2022. The difference between the opening and closing balances of the Company’s contract balances results from the timing difference between the Company’s performance and the customer’s payment.
The Company has no contract assets recognized from the costs to obtain or fulfill a contract with a customer.

NOTE 4—Stockholders' Equity
Stock Repurchase Program: On November 10, 2021, the Company's Board of Directors approved a stock repurchase program ("2021 Stock Repurchase Program") providing for the purchase of up to $20.0 million of the Company’s outstanding Class A common stock through December 31, 2023.
The timing and amount of any repurchases under the 2021 Stock Repurchase Program are determined at the discretion of the Company's management based on a number of factors, including the availability of capital, other capital allocation alternatives,
12

Table of Contents
market conditions for the Company's Class A Common Stock and other legal and contractual restrictions. The 2021 Stock Repurchase Program does not require the Company to acquire any specific number of shares and may be modified, suspended, extended or terminated by the Company without prior notice and may be executed through open market purchases, privately negotiated transactions or otherwise. All or part of the repurchases under the 2021 Stock Repurchase Program may be implemented under a Rule 10b5-1 trading plan, which would allow repurchases under pre-set terms at times when the Company might otherwise be restricted from doing so under applicable securities laws. The Company has not repurchased any shares of common stock under the 2021 Stock Repurchase Program through June 30, 2022.

Bellaire Corporation (“Bellaire”) is a non-operating subsidiary of the Company with legacy liabilities relating to closed mining operations, primarily former Eastern U.S. underground coal mining operations. Prior to 2021, Bellaire contributed $5.0 million to establish a mine water treatment trust (the "Mine Water Treatment Trust") to assure the long-term treatment of post-mining discharge. Bellaire's Mine Water Treatment Trust invests in equity securities that are reported at fair value based upon quoted market prices in active markets for identical assets; therefore, they are classified as Level 1 within the fair value hierarchy. The Company recognized a loss of $1.5 million and $2.1 million during the three and six months ended June 30, 2022, respectively, and a gain of $0.7 million and $1.0 million during the three and six months ended June 30, 2021, respectively, related to the Mine Water Treatment Trust.
Prior to 2021, the Company 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 Company recognized a loss of $0.4 million and a gain of $0.8 million during the three and six months ended June 30, 2022, respectively, and a gain of $0.6 million and $1.1 million during the three and six months ended June 30, 2021, respectively, related to the investment in these equity securities.
The gains and losses related to equity securities are reported on the line Loss (gain) on equity securities in the Other (income) expense section of the Unaudited Condensed Consolidated Statements of Operations.
As discussed in Note 1, the Company recorded the estimated fair value of an office building and membership units of a privately held company during the second quarter of 2022. These fair value measurements were based on significant inputs not observable in the market and thus represent Level 3 measurements within the fair value measurement hierarchy. Level 3 fair market values were determined using a variety of information, including estimated future cash flows and external appraisals, and considered both the income and market approaches.
The significant assumptions used in determining the fair value of the membership units are the estimated future cash flows and the discount rate applied to the estimated future cash flows. The estimate of future cash flows is based on available historical information and forecasts provided by the privately held company that are inherently uncertain. Management determined the appropriate discount rate based on the weighted average cost of capital ("WACC"). The WACC takes into account both the
13

Table of Contents
after-tax cost of debt and cost of equity. A major component of the cost of equity is the current risk-free rate on twenty-year U.S. Treasury bonds as well as company specific risk and size premiums.
In determining the $4.1 million fair value of the office building, the Company engaged an independent real estate appraiser to appraise the property utilizing observed sales transactions for similar assets as well as consideration of an income approach.
Prior to receiving the membership units from GRE, the Company held a $5.0 million investment in the same privately-held company. The Company previously elected to use the measurement alternative to fair value included in ASC 321, Investments – Equity Securities, that allows investments without readily determinable fair values to be carried at cost less impairment, if any, adjusted for observable price changes in orderly transactions for the identical or similar investments. The Company determined that the receipt of the additional membership units does not represent an observable transaction as defined in ASC 321. As such, the Company will add the fair value of the additional membership units of $12.8 million to the $5.0 million historical cost basis of the existing membership units, the total of which is the initial measurement of the Company’s equity method investment.
The office building is included in Property, plant and equipment, net and the investment in the privately-held company is included in Investment in private company equity units within the accompanying Unaudited Condensed Consolidated Balance Sheets.
There were no transfers into or out of Levels 1, 2 or 3 during the six months ended June 30, 2022 and 2021.
NOTE 6—Unconsolidated Subsidiaries
Each of the Company's wholly owned Unconsolidated Subsidiaries, within the Coal Mining and NAMining 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 NACCO and NACoal. Although NACoal owns 100% of the equity and manages the daily operations of the Unconsolidated Subsidiaries, the Company has determined that the equity capital provided by NACoal 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, the Company is not the primary beneficiary and therefore does 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 $15.4 million and $19.1 million at June 30, 2022 and December 31, 2021, respectively. The Company's maximum risk of loss relating to these entities is limited to its invested capital, which was $4.9 million and $7.6 million at June 30, 2022 and December 31, 2021, respectively. Earnings of unconsolidated operations were $14.6 million and $29.2 million during the three and six months ended June 30, 2022, respectively, and $13.5 million and $28.9 million during the three and six months ended June 30, 2021.
The contract mining agreement between Bisti and NTEC was terminated effective September 30, 2021. As of October 1, 2021, NTEC assumed control and responsibility for operation and all reclamation of the Navajo Mine.
NACoal 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”), NACoal would be obligated for payment of a "make-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 on or after January 1, 2024 by Coyote Creek’s customers, NACoal 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 NACoal since the inception of these guarantees. The Company believes that the likelihood NACoal would be required to perform under the guarantees is remote, and no amounts related to these guarantees have been recorded.
NOTE 7—Contingencies
Various legal and regulatory proceedings and claims have been or may be asserted against NACCO and certain subsidiaries relating to the conduct of their businesses. These proceedings and claims are incidental to the ordinary course of business of the Company. Management believes that it has meritorious defenses and will vigorously defend the Company 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. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or
14

Table of Contents
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, the Company discloses 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 the Company’s financial position, results of operations and cash flows of the period in which the ruling occurs, or in future periods.
NOTE 8—Business Segments
The Company’s operating segments are: (i) Coal Mining, (ii) NAMining and (iii) Minerals Management. The Company determines its reportable segments by first identifying its 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. The Company’s Chief Operating Decision Maker utilizes operating profit to evaluate segment performance and allocate resources.
The Company has items not directly attributable to a reportable segment that are not included as part of the measurement of segment operating profit, which include primarily administrative costs related to public company reporting requirements at the parent company and the financial results of Mitigation Resources and Bellaire. Mitigation Resources generates and sells stream and wetland mitigation credits (known as mitigation banking) and provides services to those engaged in permittee-responsible stream and wetland mitigation. Bellaire manages the Company’s long-term liabilities related to former Eastern U.S. underground mining activities.
All financial statement line items below operating profit (other income including interest expense and interest income, the provision for income taxes and net income) are presented and discussed within this Form 10-Q on a consolidated basis.
As discussed in Note 1, the Company retrospectively changed its computation of segment operating profit to reclassify the results of Caddo Creek and Demery from the Coal Mining segment into the NAMining segment. See Note 1 for additional discussion of the Company's reportable segments. The following tables present revenue, operating profit, depreciation expense and capital expenditures:

Item 2. - Management's Discussion and Analysis of Financial Condition and Results of Operations
(Amounts in thousands, except as noted and per share data)
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 subsidiaries (collectively, the “Company”). NACCO brings natural resources to life by delivering aggregates, minerals, reliable fuels and environmental solutions through its robust portfolio of NACCO Natural Resources businesses. The Company operates under three business segments: Coal Mining, North American Mining ("NAMining") and Minerals Management. The Coal Mining segment operates surface coal mines for power generation companies. The NAMining segment is a trusted mining partner for producers of aggregates, coal, lithium and other industrial minerals. The Minerals Management segment, which includes the Catapult Mineral Partners business, acquires and promotes the development of mineral interests. Mitigation Resources of North America® (“Mitigation Resources”) provides stream and wetland mitigation solutions.
The Company has items not directly attributable to a reportable segment that are not included as part of the measurement of segment operating profit, which primarily includes administrative costs related to public company reporting requirements at the parent company and the financial results of Mitigation Resources and Bellaire Corporation ("Bellaire"). Bellaire manages the Company’s long-term liabilities related to former Eastern U.S. underground mining activities.
Effective January 1, 2022, the Company changed the composition of its reportable segments. As a result, the Company retrospectively changed its computation of segment operating profit to reclassify the results of Caddo Creek Resources Company, LLC (“Caddo Creek”) and Demery Resources Company, LLC ("Demery") from the Coal Mining segment into the NAMining segment as these operations provide mining solutions for producers of industrial minerals, rather than for power generation. The Coal Mining segment now includes only mines that deliver coal for power generation. This segment reporting change has no impact on consolidated operating results. All prior period segment information has been reclassified to conform to the new presentation.
All financial statement line items below operating profit (other income, including interest expense and interest income, the provision for income taxes and net income) are presented and discussed within this Form 10-Q on a consolidated basis.
The Company’s operating segments are further described below:
Coal Mining Segment
The Coal Mining segment, operating as The North American Coal Corporation® ("NACoal"), operates surface coal mines under long-term contracts with power generation companies pursuant to a service-based business model. Lignite coal is surface mined in North Dakota, Texas and Mississippi. Each mine is fully integrated with its customer's operations and is the exclusive supplier of coal to its customer's facilities.
During the three and six months ended June 30, 2022, the 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”), Mississippi Lignite Mining Company (“MLMC”) and The Sabine Mining Company (“Sabine”). Each of these mines deliver their coal production to adjacent power plants or synfuels plants under long-term supply contracts. MLMC’s coal supply contract contains a take or pay provision; all other coal supply contracts are requirements contracts under which earnings can fluctuate. Certain coal supply contracts can be terminated early, which would result in a reduction to future earnings.
On May 2, 2022, Great River Energy (“GRE”) completed the sale of Coal Creek Station and the adjacent high-voltage direct current transmission line to Rainbow Energy Center, LLC (“Rainbow Energy”) and its affiliates. As a result of the completion of the sale of Coal Creek Station, the existing Coal Sales Agreement, the existing Mortgage and Security Agreement and the existing Option Agreement between GRE and Falkirk were terminated. The Company recognized a gain of $30.9 million within the accompanying Unaudited Condensed Consolidated Statements of Operations during the second quarter of 2022 as GRE paid NACoal $14.0 million in cash, as well as transferred ownership of an office building with an estimated fair value of $4.1 million, and conveyed membership units in a privately-held company involved in the ethanol industry with an estimated fair value of $12.8 million, as agreed to under the termination and release of claims agreement between Falkirk and GRE. Prior to
17

Table of Contents
receiving the membership units from GRE, the Company held a $5.0 million investment in the same privately-held company carried at cost, less impairment. Subsequent to the receipt of the additional membership units on May 2, 2022, the Company will prospectively account for the investment under the equity method of accounting. Due to a lag in financial reporting of the privately-held company, the Company has not recorded its share of earnings or losses in the three or six months ended June 30, 2022. On a go-forward basis, earnings or losses from this investment will be recorded on a one quarter lag. See Note 5 for further discussion on fair value.
The new Coal Sales Agreement (“CSA”) between Falkirk and Rainbow Energy became effective upon the closing of the transaction. Falkirk will continue to supply all coal requirements of Coal Creek Station. Falkirk will be paid a management fee and Rainbow Energy will be responsible for funding all mine operating costs, including mine reclamation, and directly or indirectly providing all of the capital required to operate the mine. The initial production period is expected to run ten years from the effective date of the CSA, but the CSA may be extended or terminated early under certain circumstances. To support the transfer to new ownership, Falkirk has agreed to a reduction in the current per ton management fee from the effective date of the new CSA through May 31, 2024. After May 31, 2024, the per ton management fee increases to a higher base in line with 2021 fee levels, and thereafter adjusts annually according to an index which tracks broad measures of U.S. inflation.
During the three and six months ended June 30, 2021, the Coal Mining segment's operating coal mines also included Bisti Fuels Company, LLC (“Bisti”). Effective September 30, 2021, the contract mining agreement between Bisti and its customer, Navajo Transitional Energy Company ("NTEC"), was terminated.
Coteau operates the Freedom Mine in North Dakota. All coal production from the Freedom Mine is delivered to Basin Electric Power Cooperative (“Basin Electric”). Basin Electric utilizes the coal at the Great Plains Synfuels Plant (the “Synfuels Plant”), Antelope Valley Station and Leland Olds Station. The Synfuels Plant is a coal gasification plant, owned by Dakota Gasification Company (“Dakota Gas’), a subsidiary of Basin Electric, that manufactures synthetic natural gas and produces fertilizers, solvents, phenol, carbon dioxide, and other chemical products for sale. During 2020, Basin Electric informed Coteau that it is considering changes that may result in modifications to its Synfuels Plant that could potentially reduce or eliminate coal requirements at the Synfuels Plant. During 2021, Bakken Energy (“Bakken”) and Basin Electric signed a non-binding term sheet to transfer ownership of the assets of Dakota Gas to Bakken. Bakken stated the closing date is expected to be April 1, 2023. The closing is subject to the satisfaction of specified conditions. As part of the term sheet between Basin Electric and Bakken, Basin Electric indicated that the Synfuels Plant will continue existing operations through 2026. Basin Electric is also considering other options for the Synfuels Plant if the transaction with Bakken does not close.
Sabine operates the Sabine Mine in Texas. All production from Sabine is delivered to Southwestern Electric Power Company's (“SWEPCO”) Henry W. Pirkey Plant (the “Pirkey Plant”). SWEPCO is an American Electric Power (“AEP”) company. AEP intends to retire the Pirkey Plant in 2023. Sabine expects deliveries to cease during the first quarter of 2023 at which time it expects to begin final reclamation. Funding for mine reclamation is the responsibility of SWEPCO.
At Coteau, Coyote Creek, Falkirk and Sabine, the Company is 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 costs, including final mine reclamation, and directly or indirectly provide all of the capital required to build and operate the mine. This contract structure eliminates exposure to spot coal market price fluctuations while providing 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 NACCO and NACoal. See Note 6 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, NACCO does not consolidate the results of these operations within its financial statements. Instead, these contracts are accounted for as equity method investments. The income before income taxes associated with these VIEs is reported as Earnings of unconsolidated operations on the Unaudited Condensed Consolidated Statements of Operations and the Company’s investment is reported on the line Investments in unconsolidated subsidiaries in the Unaudited Condensed 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 the NACCO consolidated U.S. tax return; therefore, the Income tax provision line on the Unaudited Condensed Consolidated Statements of Operations includes income taxes related to these entities. See Note 6 for further information on the Unconsolidated Subsidiaries.
The Company performs 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.
The MLMC contract is the only operating coal contract in which the Company is responsible for all operating costs, capital requirements and final mine reclamation; therefore, MLMC is consolidated within NACCO’s 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. As diesel fuel is heavily weighted among the indices used to determine the coal sales price, fluctuations in diesel fuel prices can result in significant fluctuations in earnings at MLMC.
MLMC delivers coal to the Red Hills Power Plant in Ackerman, Mississippi. The Red Hills Power Plant supplies electricity to the Tennessee Valley Authority ("TVA") under a long-term Power Purchase Agreement. MLMC’s contract with its customer runs through 2032. TVA’s power portfolio includes coal, nuclear, hydroelectric, natural gas and renewables. The decision of which power plants to dispatch is determined by TVA. Reduction in dispatch of the Red Hills Power Plant will result in reduced earnings at MLMC.
NAMining Segment
The NAMining segment provides value-added contract mining and other services for producers of industrial minerals. The segment is a primary platform for the Company’s growth and diversification of mining activities outside of the thermal coal industry. NAMining provides contract mining services for independently owned mines and quarries, creating value for its customers by performing the mining aspects of its customers’ operations. This allows customers to focus on their areas of expertise: materials handling and processing, product sales and distribution. NAMining historically operated primarily at limestone quarries in Florida, but is focused on continuing to expand outside of Florida, mining materials other than limestone and expanding the scope of mining operations provided to its customers.
NAMining utilizes both fixed price and management fee contract structures. Certain of the entities within the NAMining segment are VIEs and are accounted for under the equity method as Unconsolidated Subsidiaries. See Note 6 for further discussion.
Minerals Management Segment
The Minerals Management segment derives income primarily by leasing its 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.
During 2021 and 2020, the Minerals Management segment acquired mineral interests, primarily in the Eagle Ford and Permian Basins in Texas. During the first six months of 2022, the Minerals Management segment had capital expenditures of $1.0 million, primarily for mineral interests in the New Mexico portion of the Permian Basin. The Minerals Management segment intends to make future acquisitions of mineral and royalty interests that meet the Company’s acquisition criteria as part of its growth strategy.
The Company’s legacy royalty and mineral interests are 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 the Company’s legacy reserves were acquired as part of its historical coal mining operations.
The Minerals Management segment owns royalty interests, mineral interests, nonparticipating royalty interests, and overriding royalty interests. The Company may own more than one type of mineral and royalty interest in the same tract of land. For example, where the Company owns an overriding royalty interest in a lease on the same tract of land in which it owns a mineral interest, the overriding royalty interest in that tract will relate to the same gross acres as the mineral interest in that tract.
The Minerals Management segment will benefit from the continued development of its mineral properties without the need for investment of additional capital once mineral and royalty interests have been acquired. The Minerals Management segment does not have any investments under which it would be required to bear the cost of exploration, production or development.
19

Table of Contents
As an owner of royalty and mineral interests, the Company’s access to information concerning activity and operations of its royalty and mineral interests is limited. The Company does 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.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Refer to the discussion of the Company's Critical Accounting Policies and Estimates as disclosed on pages 45 through 46 in the Company's Annual Report on Form 10-K for the year ended December 31, 2021. The Company's Critical Accounting Policies and Estimates have not materially changed since December 31, 2021.

the "Other contract termination settlements" line within the accompanying Unaudited Condensed Consolidated Statements of Operations during the second quarter of 2022 as a result of the transactions with GRE.
Loss (gain) on equity securities represents changes in the market price of invested assets reported at fair value. The change in the second quarter of 2022 and the first six months of 2022 compared with the respective 2021 periods was due to fluctuations in the market prices of the exchange-traded equity securities.
During the second quarter of 2022, the Company’s investment held at cost, less impairment, made a distribution to its owners, including the Company. As a result, the Company recognized a gain of $0.7 million, included in Other, net within the accompanying Unaudited Condensed Consolidated Statements of Operations in the three and six months ended June 30, 2022.
See Note 5 to the Unaudited Condensed Consolidated Financial Statements for further discussion of the Other contract termination settlements and equity securities.
Income Taxes
The Company evaluates and updates its estimated annual effective income tax rate on a quarterly basis based on current and forecasted operating results and tax laws. Consequently, based upon the mix and timing of actual earnings compared to projections of earnings between entities that benefit from percentage depletion and those that do not, the effective tax rate may vary quarterly. The estimated annual effective income tax rate differs from the U.S. federal statutory rate due, in part, to the benefit from percentage depletion. Changes in the estimated annual effective tax rate result in a cumulative adjustment. The increase in the effective income tax rate for the six months ended June 30, 2022 compared with the 2021 period reflects the impact of a higher forecast of full-year pre-tax income in 2022 compared with the prior year, including the $30.9 million gain recognized as a result of the settlement under the termination and release of claims agreement with GRE.
The enactment of tax reform legislation could adversely impact the Company’s financial position and results of operations. Legislation or other changes in U.S. tax law could increase the Company’s tax liability and adversely affect its after-tax profitability. The Biden administration has proposed to increase the U.S. corporate income tax rate to 28% from 21% and eliminate certain U.S. federal income tax benefits currently available to coal mining and oil and gas exploration and development companies. Such proposed changes could have a significant impact on the Company’s effective income tax rate, cash tax expenses and deferred taxes in future periods.
LIQUIDITY AND CAPITAL RESOURCES OF NACCO
Cash Flows
The following tables detail NACCO's changes in cash flow for the six months ended June 30:

| 2022 |  | 2021 |  | Change
Operating activities: |  |  |  |  |
Net cash provided by operating activities | $ | 40,481 |  |  | $ | 29,318 |  |  | $ | 11,163 |
Investing activities: |  |  |  |  |
Expenditures for property, plant and equipment and acquisition of mineral interests | (24,918) |  |  | (16,127) |  |  | (8,791) |
Other | 2,802 |  |  | 38 |  |  | 2,764 |
Net cash used for investing activities | (22,116) |  |  | (16,089) |  |  | (6,027) |
Cash flow before financing activities | $ | 18,365 |  |  | $ | 13,229 |  |  | $ | 5,136 |

The $11.2 million change in net cash provided by operating activities was primarily due to a $34.3 million increase in net income that includes a pre-tax gain of $30.9 million related to the termination and release of claims agreement between Falkirk and GRE. The increase in net income was partially offset by $19.4 million of non-cash items recognized during the first six months of 2022, including the gain related to the receipt of membership units in a privately-held company and the transfer of the office building, as well as a $2.5 million gain on a sale of fixed assets.

Financing activities: |  |  |  |  |
Net reductions to long-term debt and revolving credit agreement | $ | (4,291) |  |  | $ | (13,881) |  |  | $ | 9,590 |
Cash dividends paid | (2,966) |  |  | (2,786) |  |  | (180) |
Net cash used for financing activities | $ | (7,257) |  |  | $ | (16,667) |  |  | $ | 9,410 |

The change in net cash used for financing activities was primarily due to fewer repayments as a result of a reduction in borrowings under the Company’s revolving line of credit during the first six months of 2022 compared with the first six months of 2021.
Financing Activities
Financing arrangements are obtained and maintained at the NACoal level. NACoal has a secured revolving line of credit of up to $150.0 million (the “NACoal Facility”) that expires in November 2025. There were no borrowings outstanding under the NACoal Facility at June 30, 2022. At June 30, 2022, the excess availability under the NACoal Facility was $119.9 million, which reflects a reduction for outstanding letters of credit of $30.1 million.
NACCO has not guaranteed any borrowings of NACoal. The borrowing agreements at NACoal allow for the payment to NACCO of dividends and advances under certain circumstances. Dividends (to the extent permitted by NACoal's borrowing agreement) and management fees are the primary sources of cash for NACCO and enable the Company to pay dividends to stockholders.
The NACoal Facility has performance-based pricing, which sets interest rates based upon NACoal achieving various levels of debt to EBITDA ratios, as defined in the NACoal 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 June 30, 2022, for base rate and LIBOR loans were 1.25% and 2.25%, respectively. The NACoal Facility has a commitment fee which is based upon achieving various levels of debt to EBITDA ratios. The commitment fee was 0.35% on the unused commitment at June 30, 2022. During the three and six months ended June 30, 2022, the average borrowing under the NACoal Facility was $2.2 million and $3.9 million, respectively, and the weighted-average annual interest rate was 2.5% in both periods.
The NACoal Facility contains restrictive covenants, which require, among other things, NACoal 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 NACoal 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, in conjunction with maintaining unused availability thresholds of borrowing capacity, as defined in the NACoal Facility, of $15.0 million. At June 30, 2022, NACoal was in compliance with all financial covenants in the NACoal Facility.
The obligations under the NACoal Facility are guaranteed by certain of NACoal's direct and indirect, existing and future
domestic subsidiaries, and is secured by certain assets of NACoal and the guarantors, subject to customary exceptions and
limitations.
The Company believes funds available from cash on hand, the NACoal Facility and operating cash flows will provide sufficient liquidity to meet its operating needs and commitments arising during the next twelve months and until the expiration of the NACoal Facility in November 2025.
Expenditures for property, plant and equipment and mineral interests
Expenditures for property, plant and equipment and mineral interests were $24.9 million during the first six months of 2022. Planned expenditures for the remainder of 2022 are expected to be approximately $15 million in the Coal Mining segment, $5 million in the NAMining segment, $12 million in the Minerals Management segment and $4 million at Mitigation Resources.
In the Coal Mining segment, elevated levels of expected capital expenditures through 2022 are primarily related to spending at MLMC as it develops a new mine area. In the NAMining segment, expected capital expenditures through 2022 are primarily for the acquisition, relocation and refurbishment of draglines as well as the acquisition of other mining equipment to support the expansion of contract mining services beyond NAMining's historical dragline-oriented model, including the acquisition of equipment to support the Thacker Pass lithium project.
Expenditures are expected to be funded from internally generated funds and/or bank borrowings.

Debt to total capitalization | 4% |  | 6% |  | (2)%

The increase in other net tangible assets at June 30, 2022 compared with December 31, 2021 was primarily due to receipt of the membership units in a privately-held company and office building that were transferred from GRE with a fair value of $12.8 million and $4.1 million, respectively. Additionally, the increase is due to:
•An increase in Property, plant and equipment due in part to land purchased by Mitigation Resources; and
•An increase in Trade accounts receivable due to higher revenue in the second quarter of 2022 compared with the fourth quarter of 2021.
Contractual Obligations, Contingent Liabilities and Commitments
Since December 31, 2021, there have been no significant changes in the total amount of NACCO's contractual obligations, contingent liabilities or commercial commitments, or the timing of cash flows in accordance with those obligations as reported on pages 50 through 51 in the Company's Annual Report on Form 10-K for the year ended December 31, 2021. See Note 6 to the Unaudited Condensed Consolidated Financial Statements for a discussion of certain guarantees related to Coyote Creek.

Second Quarter of 2022 Compared with Second Quarter of 2021
Revenues increased 28.6% in the second quarter of 2022 compared with the second quarter of 2021 due to an increase in tons delivered as a result of increased customer requirements and a higher per ton sales price at MLMC.
The following table identifies the components of change in operating profit for the second quarter of 2022 compared with the second quarter of 2021:

| Operating Profit
2021 | $ | 7,627 |
Increase (decrease) from: |
Contract termination settlement | 14,000 |
Earnings of unconsolidated operations | 1,284 |
Gain on sale of assets | 7 |
Selling, general and administrative expenses | (914) |
Gross profit | (682) |
Amortization of intangibles | (147) |
2022 | $ | 21,175 |

Operating profit increased $13.5 million in the second quarter of 2022 compared with the second quarter of 2021 due to the $14.0 million contract termination settlement from GRE recognized during the second quarter of 2022. Excluding the $14.0 million from GRE, operating profit decreased $0.5 million mainly due to an increase in selling, general and administrative expenses and a decrease in gross profit, partially offset by an increase in the earnings of unconsolidated operations.
The increase in selling, general and administrative expenses was primarily due to higher employee-related costs.
The decrease in gross profit was primarily due to an increase in the cost per ton delivered at MLMC, due in part to an increase in the cost of diesel fuel.
The increase in earnings of unconsolidated operations was primarily due to contractual price escalation and an increase in customer requirements at Coteau as well as higher customer requirements at Sabine. These increases were partially offset by a reduction in earnings as a result of the Bisti contract termination as of September 30, 2021, reduced customer demand at Falkirk and Coyote Creek and a reduction in the per ton management fee at Falkirk.

2022 | $ | 28,527 |

Operating profit increased $12.7 million in the first six months of 2022 compared with the first six months of 2021 due to the $14.0 million contract termination settlement from GRE recognized during the second quarter of 2022. Excluding the $14.0 million from GRE, operating profit decreased $1.3 million primarily due to an increase in selling, general and administrative expenses mainly due to an increase in employee-related costs and higher professional service expenses.
In addition, an increase in earnings of unconsolidated operations was primarily due to contractual price escalation and an increase in customer requirements at Coteau, partially offset by a reduction in earnings from the Bisti contract termination as of September 30, 2021.

Second Quarter of 2022 Compared with Second Quarter of 2021
Total revenues increased 14.9% in the second quarter of 2022 compared with the second quarter of 2021 primarily due to an increase in customer requirements and tons delivered at the consolidated operations as well as an increase in reimbursable costs, which have an offsetting amount in cost of sales and have no impact on operating profit.
The following table identifies the components of change in operating profit for the second quarter of 2022 compared with the second quarter of 2021:

| Operating Profit
2021 | $ | 1,698 |
Increase (decrease) from: |
Selling, general and administrative expenses | (405) |
Earnings of unconsolidated operations | (204) |
Loss on sale of assets | (18) |
Gross profit | 186 |
2022 | $ | 1,257 |

Operating profit decreased $0.4 million in the second quarter of 2022 compared with the second quarter of 2021 primarily due to an increase in selling, general and administrative expenses. The increase in selling, general and administrative expenses was mainly due to higher employee-related costs.

First Six Months of 2022 Compared with First Six Months of 2021
Total revenues increased 17.0% in the first six months of 2022 compared with the first six months of 2021 primarily due to an increase in customer requirements and tons delivered at the consolidated operations, as well as an increase in revenue related to reclamation at Caddo Creek.
The following table identifies the components of change in operating profit for the first six months of 2022 compared with the first six months of 2021:

| Operating Profit
2021 | $ | 2,355 |
Increase (decrease) from: |
Gross profit | 978 |
Selling, general and administrative expenses | (672) |
Earnings of unconsolidated operations | (118) |
Loss on sale of assets | (15) |
2022 | $ | 2,528 |

Operating profit increased $0.2 million in the first six months of 2022 compared with the first six months of 2021 primarily due to an increase in gross profit, partially offset by an increase in selling, general and administrative expenses. The increase in gross profit was primarily attributable to the earnings associated with the reclamation contract at Caddo Creek, partially offset by a decrease in gross profit from the active operations mainly due to an increase in employee-related costs. The increase in selling, general and administrative expenses was primarily due to higher employee-related costs.
MINERALS MANAGEMENT SEGMENT
FINANCIAL REVIEW
The results of operations for the Minerals Management segment were as follows for the three and six months ended June 30:

| THREE MONTHS |  | SIX MONTHS
| 2022 |  | 2021 |  | 2022 |  | 2021
Revenues | $ | 11,962 |  |  | $ | 5,608 |  |  | $ | 24,716 |  |  | $ | 11,108 |
Cost of sales | 733 |  |  | 956 |  |  | 1,481 |  |  | 1,643 |
Gross profit | 11,229 |  |  | 4,652 |  |  | 23,235 |  |  | 9,465 |
Selling, general and administrative expenses | 552 |  |  | 479 |  |  | 1,061 |  |  | 1,057 |
Gain on sale of assets | (2,396) |  |  | — |  |  | (2,527) |  |  | — |
Operating profit | $ | 13,073 |  |  | $ | 4,173 |  |  | $ | 24,701 |  |  | $ | 8,408 |

Revenues and operating profit increased significantly in the three and six months ended June 30, 2022 compared with the respective 2021 periods primarily due to favorable changes in natural gas and oil prices and $2.1 million of settlement income recognized during the first quarter of 2022. The settlement relates to the Company’s ownership interest in certain mineral rights. In addition, operating profit increased due to a $2.4 million gain on the sale of land related to legacy operations during the second quarter of 2022.
During the three and six months ended June 30, 2022, the oil and natural gas industry experienced continued improvement in commodity prices compared with the respective 2021 periods, primarily due to:
•Higher demand as the impact from COVID-19 abates;
•Changes in domestic supply and demand dynamics as well as increased discipline around production and capital investments by oil and gas companies; and
•Instability and constraints on global supply, particularly with respect to instability in Russia and Ukraine.
Oil and natural gas prices have been historically volatile and may continue to be volatile in the future. The table below demonstrates such volatility with the average price as reported by the United States Energy Information Administration for the three and six months ended June 30:

The operating loss increased $1.0 million and $1.6 million in the three and six months ended June 30, 2022, respectively, compared with the respective 2021 periods primarily due to higher employee-related costs.
NACCO Industries, Inc. Outlook
Coal Mining Outlook - 2022
Coal Mining operating profit in both the second half and for the full year of 2022 is expected to decrease significantly compared with the respective 2021 periods, both including and excluding the contract termination payments received in 2022 and 2021. The expected reduction in operating profit is primarily the result of reduced earnings at both consolidated and unconsolidated Coal Mining operations as well as an anticipated increase in operating expenses. The increase in operating expenses is primarily due to expected higher employee-related costs, professional fees and outside services.
Results at the consolidated mining operations are expected to decrease significantly in the second half of 2022 from the comparable 2021 period and the first half of 2022. This expected decrease is primarily due to an expected substantial decline in earnings at MLMC driven by an anticipated reduction in customer demand from higher than average levels in the second half of the prior year. Lower customer demand, expected cost inflation in the latter half of 2022 on diesel fuel, repairs and supplies, and higher depreciation expense related to recent capital expenditures to develop a new mine area are expected to contribute to an increase in the cost per ton in the second half of 2022. In general, cost per ton delivered is lowest when the power plant requires a consistently high level of coal deliveries, primarily because costs are spread over more tons. As a result of the anticipated increase in cost per ton, the 2022 full-year results are expected to be substantially lower than the 2021 full year.
The anticipated reduction in earnings at the unconsolidated Coal Mining operations for the second half of and full-year 2022, compared with the respective prior year periods, is expected to be driven primarily by the reduction in the per ton management fee at Falkirk from May 1, 2022 through May 31, 2024, as well as the termination of Bisti's contract as of September 30, 2021. These decreases are expected to be partly offset by higher earnings at Coteau.
Segment Adjusted EBITDA, which excludes the contract termination settlement payments of $10.3 million from Bisti's customer in 2021 and $14.0 million from GRE in 2022, is expected to decrease significantly in 2022 from 2021 primarily as a result of the forecasted reduction in operating profit partially offset by a higher add back of depreciation, depletion and amortization expense which is expected to increase in 2022. The increase in depreciation, depletion and amortization expense is primarily due to higher capital expenditures at MLMC as a result of the development of a new mine area.
Capital expenditures are expected to be approximately $15 million in the second half of 2022 and approximately $23 million for the full year. The elevated levels of capital expenditures from 2019 through 2022 relate to the necessary development of a new mine area at MLMC, which will allow continued coal deliveries through the end of the contract. The increase in capital expenditures associated with mine development will result in higher depreciation expense in future periods that will unfavorably affect future operating profit. Capital expenditures for MLMC are expected to decline significantly beginning in 2023.
The Company's contract structure at each of its coal mining operations eliminates exposure to spot coal market price fluctuations. However, fluctuations in natural gas prices and the availability of renewable power generation, particularly wind, can contribute to changes in power plant dispatch and customer demand for coal. Sustained higher natural gas prices could continue to result in increased demand for coal. Changes to expectations for customer power plant dispatch could affect the

Table of Contents
Company’s outlook for 2022 and over the longer term. The owner of the power plant served by the Company's Sabine Mine in Texas intends to retire the power plant in the first quarter of 2023, at which time Sabine expects to begin final reclamation. Funding for mine reclamation is the responsibility of the customer.
NAMining Outlook
NAMining expects operating profit to increase in both the second half of 2022 and for the full year over the respective 2021 periods. The increase in the second half is primarily due to improved fourth quarter results, principally from a shift in mix of tons delivered to operations with higher-margin contracts, partially offset by an anticipated increase in operating expenses. Segment Adjusted EBITDA for 2022 is expected to increase significantly compared with the prior year as a result of the improvement in operating profit from higher reclamation income at Caddo Creek in the first half of 2022 and the add back of higher depreciation expense.
During the first quarter of 2022, NAMining agreed to commission a new dragline at an existing quarry in Florida to secure a contract extension through 2027. This dragline will supplement an existing dragline, resulting in an expected increase in deliveries and income over the next five years at this quarry. NAMining continues to have a substantial pipeline of potential new projects and is pursuing a number of growth initiatives that, if successful, would be accretive to future earnings.
In 2019, Sawtooth Mining, LLC, entered into a mining services agreement to serve as the exclusive contract miner for the Thacker Pass lithium project in northern Nevada, owned by Lithium Nevada Corp., a subsidiary of Lithium Americas Corp. (TSX: LAC) (NYSE: LAC). Lithium Americas owns the lithium reserves at Thacker Pass and will be responsible for the processing and sale of the lithium produced. In July 2022, Lithium Americas provided an update on the Thacker Pass project, which noted that all key state-level permits had been issued for Thacker Pass and feasibility study results are expected in the second half of 2022. At maturity, this management fee contract is expected to deliver fee income similar to a mid-sized management fee coal mine.
NAMining previously forecasted capital expenditures of $28 million for 2022. NAMining now expects full-year capital expenditures to be $13 million, with approximately $5 million expended in the second half of 2022 primarily for the acquisition, relocation and refurbishment of draglines, as well as the acquisition of other mining equipment to support the continued expansion of contract-mining services. The reduction in capital expenditures from the previous forecast is due to a change in the timing of the acquisition of equipment to support the Thacker Pass lithium project from 2022 to 2023.
Minerals Management Outlook
The Minerals Management segment derives income from royalty-based leases under which lessees make payments to the Company based on their sale of natural gas, oil, natural gas liquids and coal, extracted primarily by third parties.
Excluding settlement income of $3.3 million recognized in the 2021 third quarter, operating profit and Segment Adjusted EBITDA in the second half of 2022 are expected to be comparable to the second half of 2021 but decrease significantly compared with the first half of 2022 primarily driven by current expectations for natural gas and oil prices and an anticipated reduction in production volumes. As a result of the substantial earnings in the first half of 2022, the Company expects a significant increase in full-year 2022 operating profit over 2021.
Commodity prices are inherently volatile and as an owner of royalty and mineral interests, the Company’s access to information concerning activity and operations with respect to its interests is limited. The Company's expectations are based on the best information currently available and could vary positively or negatively as a result of adjustments made by operators and/or changes to commodity prices.
In the first quarter of 2022, Minerals Management completed a small acquisition of mineral interests in the New Mexico portion of the Permian basin for $0.7 million. Minerals Management is targeting additional investments in mineral and royalty interests of approximately $12 million in the second half of 2022. These investments are expected to be accretive, but each investment's contribution to earnings is dependent on the details of that investment, including the size and type of interests acquired and the stage and timing of mineral development. The contribution of each investment could also vary due to commodity price changes. These acquired interests are expected to align with the Company’s strategy of selectively acquiring mineral and royalty interests with a balance of near-term cash-flow yields and long-term growth potential, in high-quality reservoirs offering diversification from the Company’s legacy mineral interests.
Consolidated Outlook
Overall for the 2022 full year, excluding the settlements associated with the GRE/Rainbow Energy transaction and the Bisti termination fee recognized in 2021, NACCO expects consolidated operating profit and net income to decline moderately from 2021. Lower operating profit in the Coal Mining segment is expected to be partially offset by a significant increase in earnings

Table of Contents
at the Minerals Management segment primarily from the substantial increase in Minerals Management's earnings in the first half of 2022. In addition, income realized in 2021 on exchange-traded equity securities held by the Company is not expected to reoccur due to a deterioration in public equity markets during 2022. The effective income tax rate, including the settlements associated with the GRE/Rainbow Energy transaction is expected to be between 15% and 17%. In 2022, Consolidated Adjusted EBITDA, which excludes the termination and settlement payments, is expected to be comparable to 2021.
Consolidated capital expenditures are expected to be approximately $61 million in 2022 and include approximately $12 million for expenditures at Mitigation Resources. In 2022, cash flow before financing activities is expected to be significantly lower than in 2021 as a result of the anticipated increase in capital expenditures in 2022.
Growth and Diversification
The Company is pursuing growth and diversification by strategically leveraging its core mining and natural resources management skills to build a strong portfolio of affiliated businesses. Management continues to be optimistic about the long-term outlook for growth in the NAMining and Minerals Management segments and in the Company's Mitigation Resources business. Each of these businesses continues to expand its pipeline of potential new projects with opportunities for growth and diversification.
NAMining is pursuing growth and diversification by expanding the scope of its business development activities to include potential customers who require a broad range of minerals and materials and by leveraging the Company’s core mining skills to expand the range of contract mining services it provides. NAMining continues to pursue additional opportunities to provide comprehensive mining services to operate entire mines, as it expects to do at the lithium project in Nevada. The goal is to build NAMining into a leading provider of contract mining services for customers that produce a wide variety of minerals and materials. The Company believes NAMining can grow to be a substantial contributor to operating profit, delivering unlevered after-tax returns on invested capital in the mid-teens as this business model matures and achieves significant scale, but the pace of growth will be dependent on the mix and scale of new projects.
The Minerals Management segment continues to grow and diversify by pursuing acquisitions of mineral and royalty interests in the United States. The Minerals Management segment will benefit from the continued development of its mineral properties without additional capital investment, as all further development costs are borne entirely by third-party producers who lease the minerals. This business model can deliver higher average operating margins over the life of a reserve than traditional oil and gas companies that bear the cost of exploration, production and/or development. Catapult Mineral Partners, the Company’s business unit focused on managing and expanding the Company’s portfolio of oil and gas mineral and royalty interests, has developed a strong network to source and secure new acquisitions, and has several potential acquisitions under review. The goal is to construct a high-quality diversified portfolio of oil and gas mineral and royalty interests in the United States that deliver near-term cash flow yields and long-term projected growth. The Company believes this business will provide unlevered after-tax returns on invested capital in the low-to-mid-teens as the portfolio of reserves and mineral interests grows and this business model matures.
Mitigation Resources continues to expand its business, which creates and sells stream and wetland mitigation credits and provides services to those engaged in permittee-responsible mitigation. This business offers an opportunity for growth and diversification in an industry where the Company has substantial knowledge and expertise and a strong reputation. During the first half of 2022, Mitigation Resources purchased property to establish a new mitigation bank north of Dallas/Fort Worth and established a joint venture to provide mitigation services for the Lake Ralph Hall project in Northern Texas. With these new 2022 projects, Mitigation Resources is involved in over 10 mitigation banks and permittee-responsible mitigation projects in Tennessee, Alabama, Mississippi and Texas and is making strong progress toward its goal to be a top ten U.S. provider of stream and wetland mitigation services. The Company believes that Mitigation Resources can provide solid rates of return as this business matures.
The Company also continues to pursue activities which can strengthen the resiliency of its existing coal mining operations. The Company remains 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 the Company's 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 Coal Mining segment's customers. Fluctuating natural gas prices and availability of renewable energy sources, such as wind and solar, could affect the amount of electricity dispatched from coal-fired power plants.
The Company is committed to maintaining a conservative capital structure as it continues to grow and diversify, while avoiding unnecessary risk. Strategic diversification will generate cash that can be re-invested to strengthen and expand the businesses.

Item 1A Risk Factors
During the quarter ended June 30, 2022, there have been no material changes to the risk factors previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2021, except as follows:
The value of our investment in a private company involved in the ethanol industry could decline, could be illiquid and could be volatile in terms of value and returns, which could adversely affect our financial condition and results of operations.
As of June 30, 2022, we hold a $17.8 million investment in a private company involved in the ethanol industry. Financial returns on ethanol investments are highly dependent on commodity prices, which are subject to significant volatility, uncertainty and regional supply shortages. The $17.8 million dollar valuation for this investment is based, in part, on an assumption that the private company will implement carbon capture and storage to capture carbon dioxide generated in the ethanol production process. This process increases the value of the ethanol produced by the private company. Should this capture process be delayed or not implemented, the value of this investment may be impaired. This investment is non-marketable and we may not be able to achieve a return on our investment in a timely manner, if at all. The private company's operating agreement restricts the Company's ability to transfer the membership units, resulting in a liquidity discount. Since there is no active market for the exchange of these securities, our ability to liquidate this investment will likely be dependent on a liquidity event. Valuations of privately-held companies are inherently complex and uncertain due to the lack of readily available market data for such securities. If we determine that this investment has experienced a decline in value, we will be required to recognize an impairment charge in net income.
This investment will be accounted for under the equity method under which we report our proportionate share of the net earnings or losses of this private company as a component of Income before income tax provision. If the earnings or losses of and distributions from this investment is material in any year, those earnings or losses may have a material effect on our net income, cash flows, financial condition and liquidity. We do not control the day-to-day operations of this investment; however, how the company is managed could impact our results of operations and cash flows. Additionally, this business is subject to laws, regulations, market conditions and other risks inherent in its operations. Any of these factors could adversely impact our results of operations, our cash flows and the value of our investment.
MLMC is subject to risks associated with its capital investment, operating and equipment costs, growing use of alternative generation that competes with coal fired generation, changes in customer demand and inflationary adjustments.
The profitability of MLMC is subject to the risk of loss of investment in this operation, increases in the cost of mining, changes in customer demand, growing competition from alternative power generation that competes with coal-fired generation and the emergence of adverse mining conditions. At MLMC, the costs of mining operations are not reimbursed by MLMC's customer. As such, increased costs at MLMC or decreased revenues could materially reduce the Company's profitability. Any reduction in customer demand at MLMC, including reductions related to reduced mechanical availability of the customer’s power plant, would adversely affect the Company's operating results and could result in significant impairments. MLMC has approximately $137 million of long-lived assets, including property, plant and equipment and a coal supply agreement intangible asset, which are subject to periodic impairment analysis and review. Identifying and assessing whether impairment indicators exist, or if events or changes in circumstances have occurred, including assumptions about future power plant dispatch levels, changes in operating costs and other factors that impact anticipated revenue and customer demand, requires significant judgment. Actual future operating results could differ significantly from these estimates, which may result in an impairment charge in a future period, which could have a substantial impact on the Company’s results of operations.
MLMC sells lignite at contractually agreed upon prices which are subject to changes in the level of established indices over time. As diesel fuel is heavily weighted among the indices used to determine the coal sales price, fluctuations in diesel fuel prices can result in significant fluctuations in earnings at MLMC.

MLMC delivers coal to the Red Hills Power Plant in Ackerman, Mississippi. The Red Hills Power Plant supplies electricity to TVA under a long-term PPA. MLMC’s contract with its customer runs through 2032. TVA’s power portfolio includes coal, nuclear, hydroelectric, natural gas and renewables. In 2019, TVA published its updated Integrated Resource Plan, which indicates plans to increase its reliance on solar power. A decrease in the number of days TVA dispatches the Red Hills Power Plant would reduce MLMC's customer's demand for coal. The decision of which power plants to dispatch is determined by TVA.
Choctaw Generation Limited Partnership ("CGLP") leases the Red Hills Power Plant from a Southern Company subsidiary pursuant to a leveraged lease arrangement. CGLP's ability to make required payments to the Southern Company subsidiary is dependent on the operational performance of the Red Hills Power Plant. During 2020, Southern Company revised the estimated cash flows to be received under the leveraged lease which resulted in a full impairment of the lease investment. If any future lease payment is not paid in full, the Southern Company subsidiary may be unable to make its corresponding payment to the holders of the underlying non-recourse debt related to the Red Hills Power Plant. Failure to make the required payment to the debtholders could represent an event of default that would give the debtholders the right to foreclose on, and take ownership of, the Red Hills Power Plant from the Southern Company subsidiary. A foreclosure of the Red Hills Power Plant could have a material adverse effect on MLMC's financial condition, results of operations and cash flows. Southern Company publicly disclosed that all required lease payments have been paid in full through December 31, 2021. On July 28, 2022, Southern Company disclosed in its Form 10-Q that on June 30, 2022, Southern Company provided notice to the lessee, CGLP, to terminate the related operating and maintenance agreement effective June 30, 2023. The parties to the lease agreement are currently negotiating a potential restructuring, which could result in rescission of the termination notice. The ultimate outcome of this matter cannot be determined at this time but could have a material impact on the Company's financial statements if the operating and maintenance agreement is terminated.
Similar to the Company's unconsolidated mines, all production costs at MLMC are capitalized into inventory and recognized in cost of sales as tons are delivered. In periods of limited or no deliveries, MLMC may be required to reduce its inventory carrying value using the lower of cost and net realizable value approach, which could adversely affect MLMC’s results of operations.
Changes in customer demand for any reason, including, but not limited to, reduced mechanical availability of the customer’s power plant, dispatch of power generated by other energy sources ahead of coal, fluctuations in demand due to unanticipated weather conditions, regulations or comparable policies which may promote planned and unplanned outages at the Red Hills Power Plant, economic conditions, including an economic slowdown and a corresponding decline in the use of electricity, governmental regulations and inflationary adjustments could have a material adverse effect on MLMC's financial condition, results of operations and cash flows.
