The Company’s operations are highly dependent upon the interest rate-sensitive construction and steelmaking industries. Consequently, these end markets could experience lower levels of economic activity in an environment of rising interest rates. Management has considered the current economic environment and its potential impact to the Company's business. Demand for aggregates products, particularly in the infrastructure construction market, is affected by federal, state and local budget and deficit issues. Further, delays or cancellations of capital projects in the nonresidential and residential construction markets could occur if companies and consumers are unable to obtain affordable financing for construction projects or if consumer confidence is eroded by economic uncertainty. Demand in the nonresidential and residential construction markets is affected by interest rates. While unchanged since December 31, 2025, the benchmark federal funds rate remains above the current rate of inflation, resulting in continued restrictive monetary policy. Aside from these inherent operating risks, the Company’s earnings are also affected by changes in short-term interest rates and changes in enacted tax laws. Variable-Rate Borrowing Facilities. At June 30, 2026, the Company had an $800 million Revolving Facility and a $600 million Trade Receivable Facility. Borrowings under these facilities bear interest at a variable interest rate. A hypothetical 100-basis-point increase in interest rates on variable-rate borrowings of $655 million, the combined outstanding balance at June 30, 2026, would increase interest expense by $7 million on an annual basis. Pension Expense. The Company’s results of operations are affected by its pension expense. Assumptions that affect pension expense include the discount rate and, for the qualified defined benefit pension plan only, the expected long-term rate of return on assets. Therefore, the Company has interest rate risk associated with these factors. The impact of hypothetical changes in these assumptions on the Company’s annual pension expense is discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Income Tax. Any changes in enacted tax laws, rules or regulatory or judicial interpretations, or any change in the pronouncements relating to accounting for income taxes could materially impact the Company’s effective tax rate, tax payments, cash flow, financial condition and results of operations. Energy Costs. Energy costs, including diesel fuel, natural gas, electricity, coal and petroleum coke, represent significant production costs. The Company may be unable to pass along increases in the costs of energy to customers in the form of price increases for the Company’s products. The Specialties business has varying fixed-price agreements for a portion of its 2026 energy requirements. A hypothetical 10% change in the Company’s energy prices in 2026 as compared with 2025, assuming comparable volumes, would change 2026 energy expense for continuing operations by $29 million.
