Previous report

Our contracted forward sales for accredited capacity, energy, and coal are detailed below with estimated revenue from forward sales of $2.4 billion as of June 30, 2026.

Previous report

Other operating and maintenance costs increased $5.6 million, or 52.3%, from the second quarter of 2025. The increase was driven by increased maintenance activities in connection with the planned major maintenance outage. The impacted generating unit came back online in July 2026.

Previous report

Other operating revenue decreased $2.9 million or 92.6% compared to the second quarter of 2025, which included $3.0 million of revenue received related to contractual negotiations on an exclusivity agreement that did not recur in 2026.

Previous report

or 6.4%, versus the second quarter of 2025, attributable to the 8.6% increase in our average third party price per ton, which more than offset a 2.0% decrease in tons sold to third parties.

Previous report

Other operating and maintenance costs increased $4.6 million, or 25.1%, which is largely attributable to higher mine expansion costs as well as the increase in total tons sold of 44,000, or 4.9%, versus the second quarter of 2025. Labor expenses increased $1.0 million, or 5.4%, from the second quarter of 2025, leading to a small increase in labor cost per ton sold of $0.09 per ton up to $21.62 per ton for the three months ended June 30, 2026.

Previous report

Depreciation, Depletion and Amortization increased by $4.0 million compared to the second quarter of 2025, largely as a result of a $4.8 million out-of-period adjustment recorded during the second quarter of 2025 due to an overstatement of depreciation, depletion and amortization expense in the first quarter of 2025.

Previous report

Other operating and maintenance costs increased $1.0 million, or 2.4%, which is attributable to higher mine expansion costs, offset by the decrease in total tons sold of 0.2 million, or 8.8%, versus the first six months of 2025. Labor expenses increased $1.4 million, or 3.7%, from the six months ended June 30, 2025; however, because tons sold declined 8.8%, labor cost per ton sold rose $2.66 to $22.06 per ton as production at the mine outpaced coal sales.

Previous report

Depreciation, Depletion and Amortization decreased by $1.6 million, or 15.3%, compared to the first six months of 2025.

Previous report

We are evaluating financing alternatives to fund the remaining purchase price and related costs, which may include project-level financing, structured financing arrangements supported by our contracted revenue base, proceeds from long-term offtake agreements, borrowings under our New Credit Facility, and issuances of debt or equity securities. There can be no assurance that financing will be available on acceptable terms, or at all.

Previous report

If we are unable to obtain financing on a timely basis, we may seek to renegotiate or extend the payment terms under the APA, which may not be available to us on acceptable terms or at all. If we are unable to renegotiate or extend the payment terms, a failure to make payments when due could result in termination of the APA, the forfeiture of amounts we have already paid, and other damages. In addition, our ability to incur additional indebtedness under our New Credit Facility to fund the remaining purchase price and related costs is subject to compliance with the financial covenants described under*“Item 1. Financial Statements - Note 4 – Bank Debt”* to our unaudited condensed consolidated financial

Previous wording

Segment operating revenues from electric operations decreased $0.5 million, or 0.8%, compared to the second quarter of 2025, attributable to a $3.2 million decrease in sales of delivered energy that was partially offset by a $2.8 million increase in accredited capacity revenue. The price per MWh for delivered energy decreased 20.8% year-over-year from $52.66 for the three-month period ended June 30, 2025 to $41.69 in 2026, primarily attributable to contract mix, driven by increased deliveries under lower-priced prepaid forward sales contracts. Our Electric Operations generated a slightly increased quantity of MWh and purchased an additional 0.1 million MWh for resale resulting in a net increase of energy sales of 0.1 million MWh, an increase of 17.1% compared to the second quarter of 2025. The annual planned major maintenance outages had a significant impact on the total MWh generated during both the three months ended June 30, 2026 and 2025. Accredited capacity revenue increased 17.4% to $18.6 million for the three-month period ended June 30, 2026 from $15.8 million in the comparable prior year period.

Current wording

Segment operating revenues from electric operations decreased $0.4 million, or 0.4%, compared to the third quarter of 2025, attributable to a $3.6 million decrease in sales of delivered energy that was partially offset by a $3.2 million increase in accredited capacity revenue. The price per MWh for delivered energy decreased 3.1% year-over-year from $49.29 for the three-month period ended September 30, 2025 to $47.76 in 2026, primarily attributable to contract mix, driven by increased deliveries under lower-priced prepaid forward sales contracts. Our Electric Operations generated 0.1 million lower MWh, offset by the purchase of an additional 0.1 million MWh for resale resulting in a 1.6% reduction in total MWh sold compared to the third quarter of 2025. Accredited capacity revenue increased 20.8% to $18.7 million for the three-month period ended September 30, 2026 from $15.5 million in the comparable prior year period driven by improved prices.

Previous wording

Fuel costs on a segment basis increased $3.9 million, or 18.4%, from the second quarter of 2025. The increase is due to electric power generation increasing by 5.7% coupled with an increase in the cost of coal consumed of 2.7%, from $53.38 per ton in 2025 to $54.82 per ton in 2026 along with an increase in tons consumed. Fuel costs on a consolidated basis were relatively unchanged from the second quarter of 2025 at $14.7 million, as fewer tons purchased from third parties, reflecting a heavier reliance on coal from Sunrise, offset a 6.0% increase in the average price per ton of coal purchased from third parties. Natural gas pricing did not impact the demand for coal, as the average spot price at Chicago citygate only increased by $0.02 per thousand cubic feet to $2.94 per thousand cubic feet in April 2026 compared to April 2025. The weather year-over-year had a muted impact on the demand for electricity.

Current wording

Fuel costs on a segment basis decreased $1.3 million, or 2.9%, from the third quarter of 2025. The decrease includes a $2.6 million coal inventory adjustment recorded in the third quarter of 2025 that did not recur in 2026, partially offset by higher non-coal fuel costs, primarily fuel oil consumed during the start-ups. Coal costs decreased $0.3 million, due to lower electric power generation of 8.0% and the benefit of the coal mix used, partially offset by a higher burn rate and an increase in the cost of coal consumed of 2.4%, from$54.22 per ton in 2025 to$55.51 per ton in 2026. Fuel costs on a consolidated basis increased$1.6 million, or 6.1%, reflecting a heavier reliance on coal from third-parties combined with a 6.2% increase in the average price per ton of coal purchased from third parties. Weather and natural gas pricing had a muted impact on the demand for coal, as the average spot price at Chicago citygate increased $0.10 per thousand cubic feet to $3.75 per thousand cubic feet in July 2026 compared to July 2025.

Our effective tax rate (“ETR”) is estimated at ~6.4% and ~0% for the six months ended June 30, 2026 and 2025, respectively. For the six months ended June 30, 2026, we estimated our annual ETR based upon projected annual income (loss), forecasted permanent tax differences, discrete items, and statutory rates in states in which we operate. Our ETR differs from the statutory rate due primarily to statutory depletion in excess of tax basis and changes in the valuation allowance. The deduction for statutory percentage depletion does not necessarily change proportionately to changes in income (loss) before income taxes.

Current wording

Our effective tax rate (“ETR”) is estimated at ~0% for the nine months ended September 30, 2026 and 2025, respectively. Income tax expense of $1.8 million was recorded in the three months ended September 30, 2026, compared with a year-to-date income tax benefit of $1.7 million recorded through June 30, 2026. The change reflects a decrease in our estimated annual ETR. At June 30, 2026, we forecasted full-year pretax income, whereas at September 30, 2026, we forecast a full-year pretax loss, primarily due to financing costs related to the KLIM Facility, including the loss on extinguishment of the TCB Credit Facility and interest expense, and expected operating results. Our annual income tax estimate primarily reflects the change in our net deferred tax liability that is not offset by net operating loss carryforwards, which are limited to 80% of taxable income. For the nine months ended September 30, 2026, we estimated our annual ETR based upon projected annual income (loss), forecasted permanent tax differences, discrete items, and statutory rates in states in which we operate. Our ETR differs from the statutory rate due primarily to the valuation allowance and, historically, statutory depletion in excess of tax basis. The deduction for statutory percentage depletion does not necessarily change proportionately to changes in income (loss) before income taxes.
