During the three and six months ended June 30, 2024, 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”) and Mississippi Lignite Mining Company (“MLMC”). Each of these mines supply lignite coal for power generation and delivers its coal production to an adjacent power plant or synfuels plant under a long-term supply contract. While MLMC’s coal supply contract contains a take or pay provision, the contract contains a force majeure provision that allows for the temporary suspension of the take or pay provision during the duration of certain specified events beyond the control of either party; all other coal supply contracts are requirements contracts. Certain coal supply contracts can be terminated early, which would result in a reduction to future earnings.

Current wording

Previous efforts by the EPA were met with extensive litigation and there has been a similar response to the new GHG and MATS rules. State coalitions have filed lawsuits challenging both of these rules. Several other entities, including electric generators and industry groups, have joined the lawsuits. In July 2024 and October 2024, stay motions for the GHG and MATS rules were denied by the U.S. Court of Appeals for the District of Columbia Circuit (the “D.C. Circuit Court”), respectively. Following the D.C. Circuit Court denial, emergency stay motions were filed for the GHG and MATS rules with the Supreme Court of the United States ("SCOTUS”). In October 2024, the SCOTUS denied the stay applications for the GHG and MATS rules. The GHG and MATS cases will continue through the normal procedures in the D.C. Circuit Court without stays in place. The Company cannot predict the full impact of the MATS and GHG rules on the operations of the coal-fired generation facilities operated by its customers.

Substantially all of the Coal Mining segment's profits are derived from long-term mining contracts. These new rules may raise the cost of fossil fuel generated energy, making coal-fired power plants less competitive, and/or result in early closure which could have an adverse impact on demand for coal and ultimately result in the early closure of the mines servicing these plants, including closure of the Company's coal mines. Any such closure of the Company's mines could have a material adverse effect on the Company’s business, financial condition and results of operations.

Previous wording

The EPA promulgated a regional haze program designed to protect and to improve visibility at and around Class I Areas, which are generally National Parks, National Wilderness Areas and International Parks. State implementation of the EPA’s Regional Haze Rule could require Coyote Creek’s customers to incur significant new costs at the Coyote Station power plant, which could result in the premature closure of the power plant and the Coyote Creek mine. The North Dakota Department of Environmental Quality (“NDDEQ”) finalized its state implementation plan and submitted it to the EPA for approval in August 2022. The NDDEQ determined that visibility progress was being made and did not require significant emissions controls at Coyote Station power plant. Notwithstanding NDDEQ’s determination, the EPA may require additional costly emission controls and it may not be economically feasible for Coyote Creek's customers to invest in such equipment, which could result in early retirement of Coyote Station and the Coyote Creek mine. In July 2024, the EPA issued a proposed partial denial of the state implementation plan. The Company plans to submit comments to the EPA on the proposed partial denial.

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 and may make quarterly comparisons not meaningful. The benefit of percentage depletion is not directly related to the amount of consolidated pre-tax income recorded in a period. Accordingly, in periods where income before tax is relatively small, the proportional effect of the benefit from percentage depletion on the effective tax rate may be significant. In addition, as a result of a forecasted full-year 2023 loss before income tax as of June 30, 2023, the effect of the benefit from percentage depletion resulted in a negative forecasted effective tax rate. Each quarter, the Company updates its estimate of the annual effective tax rate and the cumulative impact of the change in the estimated annual tax rate is recorded, which can additionally make quarterly comparisons not meaningful.

Changes in the level of coal inventory and costs capitalized into inventory also contributed to the improvement as the decrease in demand resulted in an increase in the coal stockpile and an increase in costs capitalized into inventory during the first six months of 2024. Cost of sales in the first six months of 2023 was higher as the coal stockpile was reduced during the move to a new mine area and prior period production costs were recognized into income. In addition, gross loss in the first six months of 2024 and 2023 included $3.1 million and $4.2 million of inventory impairment charges, respectively, to write down MLMC's coal inventory to its net realizable value.

Previous wording

Total revenues increased 28.6% in the second quarter of 2024 compared with the second quarter of 2023, primarily due to an increase in reimbursable costs, which have an offsetting amount in cost of sales and have no impact on operating profit. An increase in demand at the consolidated quarries also contributed to the improvement in total revenues.

Current wording

Total revenues increased 48.8% in the third quarter of 2024 compared with the third quarter of 2023, primarily due to an increase in reimbursable costs, which have an offsetting amount in cost of sales and have no impact on gross profit. Revenues excluding reimbursable costs increased 24.1% mainly due to favorable pricing and delivery mix at the consolidated limestone quarries. This increase was partially offset by a reduction in tons delivered primarily due to an increase in planned customer outages and significant rain events in Florida during the third quarter of 2024.
