For the nine months ended September 30, 2024, the Company recorded income tax expense of $15,356 on income before income taxes of

On July 4, 2025, President Trump signed into law legislation commonly referred to as the “One Big Beautiful Bill Act” (“OBBBA”). Changes made by the OBBBA include the reinstatement of 100% bonus depreciation, the reinstatement of immediate expensing for domestic research and experimentation costs, changes to the calculation of the foreign-derived intangible income deduction and the interest expense limitation, and the addition of metallurgical coal to the list of “applicable critical minerals” for purposes of the Section 45X credit. The Section 45X credit (also known as the advanced manufacturing production credit), as amended, provides a refundable tax credit equal to 2.5% of the production costs for metallurgical coal produced during tax years 2026 through 2029. The Company incorporated the effects of the OBBBA in its income tax provision for the quarter ended September 30, 2025 and noted no material impacts to the Company’s estimated annual effective tax rate.
