Notes to Condensed Consolidated Financial Statements

1. Basis of Presentation

The condensed consolidated financial statements included herein have been prepared by United States Lime & Minerals, Inc. (the “Company”) without independent audit. In the opinion of the Company’s management, all adjustments of a normal and recurring nature necessary to present fairly the financial position, results of operations, and cash flows for the periods presented have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2025. The results of operations for the three- and six-month periods ended June 30, 2026 are not necessarily indicative of operating results for the full year.

2. Organization

The Company is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road, and building contractors), industrial (including paper and glass manufacturers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), metals (including steel producers), roof shingle manufacturers, agriculture (including poultry producers), and oil and gas services industries. The Company is headquartered in Dallas, Texas and operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Missouri, Oklahoma, and Texas through its wholly owned subsidiaries, Arkansas Lime Company, ART Quarry TRS LLC (DBA Carthage Crushed Limestone), Colorado Lime Company, Mill Creek Dolomite, LLC, Texas Lime Company, U.S. Lime Company, U.S. Lime Company-Shreveport, U.S. Lime Company-St. Clair, and U.S. Lime Company-Transportation. In addition, the Company, through its wholly owned subsidiary, U.S. Lime Company-O & G, LLC, has royalty and non-operated working interests in natural gas wells located in Johnson County, Texas, in the Barnett Shale Formation.

3. Accounting Policies

Revenue Recognition. The Company recognizes revenue for its lime and limestone operations when (i) a contract with the customer exists and the performance obligations are identified; (ii) the price has been established; and (iii) the performance obligations have been satisfied, which is generally upon shipment. The Company’s returns and allowances are minimal. Revenues include external freight billed to customers, with related costs accounted for as fulfillment costs and included in cost of revenues. External freight billed to customers included in 2026 and 2025 revenues was$15.2 million and $12.2 million, for the respective three-month periods ended June 30, and $26.9 million and $23.6 million for the respective six-month periods ended June 30, which approximates the amount of external freight included in cost of revenues. Sales taxes billed to customers are not included in revenues.

Trade Receivables, Net. The majority of the Company’s trade receivables are unsecured. Payment terms for all trade receivables are based on the underlying purchase orders, contracts, or purchase agreements, and are generally fixed, short-term, and do not contain a significant financing component. The Company estimates credit losses relating to trade receivables based on an assessment of the current and forecasted probability of collection, historical trends, economic conditions, and other significant events that may impact the collectability of trade receivables. Due to the relatively homogenous nature of its trade receivables, the Company does not believe there are any meaningful asset-specific differences within its trade receivables portfolio that would require the portfolio to be grouped below the consolidated level for review of credit losses. Credit losses relating to trade receivables have generally been within management expectations and historical trends. Uncollected trade receivables are charged-off when identified by management to be unrecoverable. The Company maintains an allowance for credit losses to reflect currently expected estimated losses resulting from the failure of customers to make required payments.

New Accounting Pronouncements. In November 2024, the Financial Accounting Standards Board issued guidance that requires disclosure of specified information about certain costs and expenses in the notes to the Consolidated Financial

Statements (“ASU 2024-03”). ASU 2024-03 requires, among other things, that public business entities include tabular and qualitative disclosures that disaggregate each relevant expense caption on the face of a statement of income and include certain natural expenses relevant to the Company. ASU 2024-03 is to be applied on a prospective basis and is effective for annual reporting periods beginning after December 15, 2026. This ASU will result in additional disclosures being included in the Company’s consolidated financial statements once adopted.

4. Reportable Segment

The Company is managed asone reportable segment, lime and limestone operations, based on the distinctness of the Company’s activities and products. All operations are in the United States. The Company has determined that the activities of its natural gas interests and the associated level of review of those activities by the chief operating decision maker (“CODM”) precluded the natural gas activities from meeting the definition of an operating segment.

The Company’s CODM is the chief executive officer. The Company’s lime and limestone operations segment derives revenues from the sale of crushed limestone, pulverized limestone, aggregate, quicklime, hydrated lime, and lime slurry.

In evaluating the operating results of the Company, the CODM assesses performance for the lime and limestone operations segment and decides how to allocate resources (including, but not limited to, decisions on fuel blends, capital investments, and staffing levels) based on net income that is also reported on the Consolidated Statements of Operations. The measure of segment assets is reported on the Consolidated Balance Sheets as “Total assets,” and the measure of segment capital expenditures is reported on the Consolidated Statements of Cash Flows as “Purchase of property, plant, and equipment.”

The following table presents revenue, significant expenses, and profit for the three- and six-month periods ended June 30, 2026 and 2025, as reviewed and used by the CODM (in thousands). There are no other significant segment items or reconciling items to consolidated net income.

5. Income and Dividends Per Share of Common Stock

The following table sets forth the computation of basic and diluted income per common share (in thousands, except per share amounts):

The Company paid $0.06 of cash dividends per share of common stock in each of the three-month periods ended June 30, 2026 and 2025. The Company paid$0.12 of cash dividends per share of common stock in each of the six-month periods ended June 30, 2026 and 2025.

6. Inventories

Inventories are valued principally at the lower of cost, determined using the average cost method, or net realizable value. Costs for raw materials and finished goods include materials, labor, and production overhead. A summary of inventories is as follows (in thousands):

7. Banking Facilities and Debt

The Company’s credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of August 3, 2023, provides for a$75 million revolving credit facility (the “Revolving Facility”) and an incremental four-year accordion feature to borrow up to an additional$50 million on the same terms, subject to approval by the Lender or another lender selected by the Company. The credit agreement also provides for a$10 million letter of credit sublimit under the Revolving Facility. The Revolving Facility and any incremental loans mature on August 3, 2028.

Interest rates on the Revolving Facility are, at the Company’s option, SOFR, plus a SOFR adjustment rate of 0.10%, plus a margin of 1.000% to 2.000%, or the Lender’s Prime Rate, plus a margin of 0.000% to 1.000%, and a commitment fee range of 0.225% to 0.350% on the undrawn portion of the Revolving Facility. The Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based upon the

Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion, amortization, and stock-based compensation expense (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period. Pursuant to a security agreement, dated August 25, 2004, the Revolving Facility is secured by the Company’s existing and hereafter acquired tangible assets, intangible assets, and real property. The maturity of the Revolving Facility and any incremental loans can be accelerated if any event of default, as defined under the credit agreement, occurs. The Company’s maximum Cash Flow Leverage Ratio is 3.50 to 1.

The Company may pay dividends so long as it remains in compliance with the provisions of the Company’s credit agreement, and it may purchase, redeem, or otherwise acquire shares of its common stock so long as its pro forma Cash Flow Leverage Ratio is less than 3.00 to 1.00 and no default or event of default exists or would exist after giving effect to such stock repurchase.

As of June 30, 2026, the Company hadno debt outstanding and no draws on the Revolving Facility other than $4.6 million of letters of credit, principally related to the new kiln project at the Texas Lime Company plant, which count as draws against the available commitment under the Revolving Facility.

8. Leases

The Company has operating leases for the use of equipment, corporate office space, and some of its terminal and distribution facilities. The leases have remaining lease terms of 0 to 8 years, with a weighted-average remaining lease term of 3 years and 4 years at June 30, 2026 and December 31, 2025, respectively. Some operating leases include options toextend the leases for up to 5 years and are only considered in the lease terms if the Company is reasonably certain it will exercise the option to extend.

The components of net operating lease costs for the three- and six-month periods ended June 30, 2026 and 2025 were as follows (in thousands):

As of June 30, 2026, future minimum payments under operating leases that were either non-cancelable or subject to significant penalty upon cancellation, including future minimum payments under renewal options that the Company is reasonably certain to exercise, were as follows (in thousands):

Supplemental cash flow information pertaining to the Company’s leasing activity for the six months ended June 30, 2026 and 2025 is as follows (in thousands):

9. Income Taxes

The Company has estimated that its effective income tax rate for 2026 will be 21.6%. The primary reason for the effective income tax rate being above the federal statutory rate is due to state income taxes, partially offset by statutory depletion, which is allowed for income tax purposes and is a permanent difference between net income for financial reporting purposes and taxable income.

10. Dividends

On June 12, 2026, the Company paid$1.7 million in cash dividends, based on a dividend of$0.06 per share of its common stock, to stockholders of record at the close of business on May 22, 2026. On March 13, 2026, the Company paid$1.7 million in cash dividends, based on a dividend of$0.06 per share of its common stock, to stockholders of record at the close of business on February 20, 2026.

11. Subsequent Event
