UNITED STATES LIME & MINERALS, INC. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

(Unaudited)

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, 2024. The results of operations for the three- and nine-month periods ended September 30, 2025 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 2025 and 2024 revenues was $13.7 million and $12.3 million, for the respective three-month periods ended September 30, and $37.3 million and $34.5 million, for the respective nine-month periods ended September 30, which approximates the amount of external freight included in cost of revenues. Sales taxes billed to customers are not included in revenues. For its natural gas interests, the Company recognizes revenue in the month of production and delivery.

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 accounts 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.

4. Reportable Segment

In November 2023, the Financial Accounting Standards Board amended guidance in ASC 280, *Segment Reporting* ("ASC 280"), by issuing Accounting Standards Update 2023-07, which updated the disclosure requirements for reportable segments, primarily through requiring enhanced disclosures about significant segment expenses. The Company adopted this guidance in the fourth quarter 2024, with retrospective application to prior reportable periods.

The Company is managed as one reportable segment, lime and limestone operations, based on the distinctness of the Company's activities and products. All operations are in the United States. During 2024, the Company 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, as provided in ASC 280. In addition, previously unallocated items, including cash, interest income and expense, and other expense are now included as part of lime and limestone operations, and consolidated net income is now used as the measure of segment profit or loss. Segment disclosures for the three- and nine-month periods ended September 30, 2024 have been recast to be consistent with the presentation for the periods ended September 30, 2025.

The Company's CODM is the chief executive officer. The Company's lime and limestone operations 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 income. 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 nine-month periods ended September 30, 2025 and 2024, as reviewed and used by the CODM. There are no other significant segment items or reconciling items to consolidated net income.

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Stock options are considered anti-dilutive if the exercise price exceeds the average per share market price for the period. No stock options were excluded for any of the periods presented above due to being anti-dilutive.

The Company paid $0.06 and $0.18 of cash dividends per share of common stock in the three- and nine-month periods ended September 30, 2025, respectively. The Company paid $0.05 and $0.15 of cash dividends per share of common stock in the three- and nine-month periods ended September 30, 2024, respectively.

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. Inventories consisted of the following (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 September 30, 2025, the Company had no debt outstanding and no draws on the Revolving Facility other than $4.7 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 4 years at both September 30, 2025 and December 31, 2024. Some operating leases include options to extend 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 lease costs for the three- and nine-month periods ended September 30, 2025 and 2024 were as follows (in thousands):

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
|  | | **Three Months Ended September 30,**  | **Three Months Ended September 30,**  | **Nine Months Ended September 30,**  | **Nine Months Ended September 30,**  |
|  | <br>**Classification** | **2025** | **2024** | **2025** | **2024** |
| Operating lease costs<sup>(1)</sup> | Cost of revenues | $998 | $700 | $2697 | $1948 |
| Operating lease costs<sup>(1)</sup> | Selling, general and administrative expenses | 78 | 76 | 240 | 229 |

| Net operating lease costs |  | $965 | $716 | $2699 | $1834 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Includes the costs of leases with a term of one year or less.

| Cash payments for lease liabilities included in operating cash flows | $1510 | $1450 |
| Right-of-use assets obtained in exchange for operating lease obligations | $368 | $827 |

---

9. Income Taxes

The Company has estimated that its effective income tax rate for 2025 will be 21.1%. 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.

On July 4, 2025, the One Big Beautiful Bill Act (the "OBBBA") was signed into law. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act of 2017, including 100% bonus depreciation. The OBBBA did not have a material impact on the Company's effective income tax rate for 2025, but it did reduce the Company's cash tax outflows for the remainder of 2025 from what they would have been under the previous federal tax law.

10. Dividends

On September 12, the Company paid $1.7 million in cash dividends, based on a dividend of $0.06 per share of its common stock, to shareholders of record at the close of business on August 22, 2025. On June 13, 2025, the Company paid $1.7 million in cash dividends, based on a dividend of $0.06 per share of its common stock, to shareholders of record at the close of business on May 23, 2025. On March 14, 2025, the Company paid $1.7 million in cash dividends, based on a dividend of $0.06 per share of its common stock, to shareholders of record at the close of business on February 21, 2025.

11. Subsequent Event

On October 29, 2025, the Company's Board of Directors declared a regular quarterly cash dividend of $0.06 per share on the Company's common stock. This dividend is payable on December 12, 2025, to shareholders of record at the close of business on November 21, 2025.

**Overview.**

We are 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. We are headquartered in Dallas, Texas and operate lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Missouri, Oklahoma, and Texas through our 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.

Our revenues increased 14.1% and 19.8% in the third quarter and first nine months 2025, respectively, compared to the third quarter and first nine months 2024. Revenues increased in the third quarter 2025, compared to the third quarter 2024, primarily due to an 8.9% increase in sales volumes of our lime and limestone products, which was principally due to increased demand from our construction, environmental, and steel customers, partially offset by decreased demand from our oil and gas services customers, and a 5.1% increase in the average selling prices for our lime and limestone products. Revenues increased in the first nine months 2025, compared to the first nine months 2024, primarily due to a 13.3% increase in sales volumes of our lime and limestone products, which was principally due to increased demand from our construction, including for the construction of large data centers, environmental, and steel customers, partially offset by decreased demand from our oil and gas services customer, and a 6.6% increase in the average selling prices for our lime and limestone products. Looking ahead, we anticipate ongoing data center construction demand being partially offset by softer demand from some of the other industries that we serve.

Our gross profit increased 21.1% and 29.2% in the third quarter and first nine months 2025, respectively, compared to the third quarter and first nine months 2024. The increases in gross profit for the 2025 periods resulted primarily from the increases in revenues discussed above.

In 2024, we began construction on a new vertical kiln and related equipment and infrastructure at our Texas Lime Company plant. We estimate that the construction costs of the Texas kiln project will total approximately $65 million and be completed in 2026.

**Liquidity and Capital Resources.**

Net cash provided by operating activities was $119.4 million in the first nine months 2025, compared to $87.4 million in the first nine months 2024, an increase of $32.0 million, or 36.6%. Our net cash provided by operating activities is composed of net income, depreciation, depletion, and amortization ("DD&A"), deferred income taxes, stock-based compensation, other non-cash items included in net income, and changes in working capital. In the first nine months 2025, net cash provided by operating activities was principally composed of $103.7 million net income, $18.5 million DD&A, and $6.2 million stock-based compensation, partially offset by a $9.4 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first nine months 2025 included increases of $15.3 million in trade receivables, net, due primarily to increased sales in the third quarter 2025 compared to the fourth quarter 2024, and $1.0 million in inventories, partially offset by a decrease of $2.3 million in prepaid expenses and other current assets and an increase of $4.5 million in accounts payable and accrued expenses. In the first nine months 2024, net cash provided by operating activities was principally composed of $81.8 million net income, $18.1 million DD&A, and $3.6 million stock-based compensation, partially offset by $0.8 million deferred income taxes and a $15.3 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first nine months 2024 included an increase of $14.9 million in trade receivables, net, due primarily to increased sales in the third quarter 2024 compared to the fourth quarter 2023, and an increase of $3.5 million in inventories, partially offset by a decrease of $1.9 million in prepaid expenses and other current assets and an increase of $1.2 million in accounts payable and accrued expenses.

We had $42.8 million in capital expenditures in the first nine months 2025, compared to $16.4 million in the first nine months 2024. Capital expenditures in the first nine months 2025 included $20.8 million related to the Texas kiln project. Net cash used in financing activities was $5.4 million in the first nine months 2025, compared to $4.3 million in the first nine months 2024, consisting primarily of cash dividends paid in each period.

Cash and cash equivalents increased $71.5 million to $349.5 million at September 30, 2025 from $278.0 million at December 31, 2024.

We are not committed to any planned capital expenditures until actual orders are placed for equipment. As of September 30, 2025, we were committed to $28.8 million of open purchase orders related to the Texas kiln project. We did not have any other material commitments for open purchase orders. As of September 30, 2025, we had incurred a total of $24.8 million on the Texas kiln project, of which $22.1 million had been paid in cash.

Our 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 us. 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 our 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 our Cash Flow Leverage Ratio, defined as the ratio of our 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 our 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. Our maximum Cash Flow Leverage Ratio is 3.50 to 1.

We may pay dividends so long as we remain in compliance with the provisions of our credit agreement, and we may purchase, redeem or otherwise acquire shares of our common stock so long as our 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.

At September 30, 2025, we had no debt outstanding and no draws on the Revolving Facility other than $4.7 million of letters of credit, principally related to the Texas kiln project, which count as draws against the available commitment under the Revolving Facility. We believe that, absent a significant acquisition, cash on hand and cash flows from operations will be sufficient to meet our operating needs, ongoing capital needs, including current and possible future modernization, expansion, and development projects, and liquidity needs and allow us to pay regular quarterly cash dividends for the near future.

**Results of Operations.**

Revenues in the third quarter 2025 were $102.0 million, compared to $89.4 million in the third quarter 2024, an increase of $12.6 million, or 14.1%. For the first nine months 2025, revenues were $284.8 million, compared to $237.7 million in the first nine months 2024, an increase of $47.1 million, or 19.8%. The increases in our revenues in the third quarter and first nine months 2025, compared to the comparable 2024 periods, resulted from increased sales volumes of our lime and limestone products, principally due to increased demand from our construction, environmental, and steel customers, partially offset by decreased demand from our oil and gas services customers, and an increase in the average selling prices for our lime and limestone products.

Gross profit was $52.2 million in the third quarter 2025, compared to $43.1 million in the third quarter 2024, an increase of $9.1 million, or 21.1%. Gross profit was $140.2 million in the first nine months 2025, compared to $108.5 million in the first nine months 2024, an increase of $31.7 million, or 29.2%. The increases in gross profit in the third quarter and first nine months 2025, compared to the comparable 2024 periods, resulted primarily from the increased revenues discussed above.

Selling, general, and administrative ("SG&A") expenses were $5.9 million in the third quarter 2025, compared to $5.0 million in the third quarter 2024, an increase of $1.0 million, or 19.1%. SG&A expenses were $18.4 million in the first nine months 2025, compared to $14.7 million in the first nine months 2024, an increase of $3.7 million, or

25.0%. The increases in SG&A expenses in the 2025 periods, compared to the comparable 2024 periods, were primarily due to increased personnel expenses, including stock-based compensation.

Other (income) expense, net was $3.4 million income in the third quarter 2025 and $9.6 million income in the first nine months 2025, compared to $3.1 million income in the third quarter 2024 and $8.4 million income in the first nine months 2024. The increases of $0.4 million and $1.2 million in other (income) expense, net during the 2025 periods, compared to the comparable 2024 periods, were primarily due to interest earned on higher average balances of our cash and cash equivalents.

Income tax expense was $10.9 million and $27.7 million in the third quarter and first nine months 2025, respectively, compared to $7.8 million and $20.4 million in the third quarter and first nine months 2024, respectively. The increases in income tax expense in the 2025 periods, compared to the comparable 2024 periods, were due to the increases in income before taxes.

On July 4, 2025, the OBBBA was signed into law. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act of 2017, including 100% bonus depreciation. The OBBBA did not have a material impact on our effective income tax rate for 2025, but it did reduce our cash tax outflows for the remainder of 2025 from what they would have been under the previous federal tax law.

Our net income was $38.8 million ($1.35 per share diluted) in the third quarter 2025, compared to net income of $33.4 million ($1.16 per share diluted) in the third quarter 2024, an increase of $5.4 million, or 16.3%. For the first nine months 2025, our net income was $103.7 million ($3.61 per share diluted), compared to $81.8 million ($2.85 per share diluted) for the first nine months 2024, an increase of $21.9 million, or 26.7%.

ITEM 4:&nbsp;&nbsp;&nbsp;&nbsp; CONTROLS AND PROCEDURES

Our management, with the participation of our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Report. Based upon that evaluation, the CEO and CFO concluded that our disclosure controls and procedures as of the end of the period covered by this Report were effective.

No change in our internal control over financial reporting occurred during the most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II.&nbsp;&nbsp;&nbsp;&nbsp; OTHER INFORMATION

ITEM 2:&nbsp;&nbsp;&nbsp;&nbsp; UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Our Amended and Restated 2001 Long-Term Incentive Plan, as Amended and Restated, allows employees and directors to pay the exercise price for stock options and the tax withholding liability upon the lapse of restrictions on restricted stock by payment in cash and/or delivery of shares of common stock. There were no repurchases in the third quarter 2025 pursuant to these provisions or otherwise.

ITEM 4:&nbsp;&nbsp;&nbsp;&nbsp;MINE SAFETY DISCLOSURES

Under Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of SEC Regulation S-K, each operator of a coal or other mine is required to include disclosures regarding certain mine safety results in its periodic reports filed with the SEC. The operation of our quarries, underground mines and plants is subject to regulation by the federal Mine Safety and Health Administration ("MSHA") under the Federal Mine Safety and Health Act of 1977. The required information regarding certain mining safety and health matters, broken down by mining complex, for the quarter ended September 30, 2025, is presented in Exhibit 95.1 to this Report.

We believe we are responsible to employees to provide a safe and healthy workplace environment. We seek to accomplish this by: training employees in safe work practices; openly communicating with employees; following safety

standards and establishing and improving safe work practices; involving employees in safety processes; and recording, reporting and investigating accidents, incidents and losses to avoid reoccurrence.

Following passage of the Mine Improvement and New Emergency Response Act of 2006, MSHA significantly increased the enforcement of mining safety and health standards on all aspects of mining operations. There has also been an increase in the dollar penalties assessed for citations and orders issued in recent years.

## Exhibit 95.1

**EXHIBIT 95.1**

**MINE SAFETY DISCLOSURES** 

The following disclosures are provided pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of SEC Regulation S-K, which require certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934, as amended, that operate mines regulated under the Federal Mine Safety and Health Act of 1977 (the "Mine Act").

The Mine Act has been construed as authorizing MSHA to issue citations and orders pursuant to the legal doctrine of strict liability, or liability without fault. If, in the opinion of an MSHA inspector, a condition that violates the Mine Act or regulations promulgated pursuant to it exists, then a citation or order will be issued regardless of whether the operator had any knowledge of, or fault in, the existence of that condition. Many of the Mine Act standards include one or more subjective elements, so that issuance of a citation or order often depends on the opinions or experience of the MSHA inspector involved and the frequency and severity of citations and orders will vary from inspector to inspector.

Whenever MSHA believes that a violation of the Mine Act, any health or safety standard, or any regulation has occurred, it may issue a citation or order which describes the violation and fixes a time within which the operator must abate the violation. In some situations, such as when MSHA believes that conditions pose a hazard to miners, MSHA may issue an order requiring cessation of operations, or removal of miners from the area of the mine, affected by the condition until the hazards are corrected. Whenever MSHA issues a citation or order, it has authority to propose a civil penalty or fine, as a result of the violation, that the operator is ordered to pay.

The table that follows reflects citations, orders, violations and proposed assessments issued to the Company by MSHA during the quarter ended September 30, 2025, and all pending legal actions as of September 30, 2025. Due to timing and other factors, the data may not agree with the mine data retrieval system maintained by MSHA. The proposed assessments for the quarter ended September 30, 2025 were taken from the MSHA system as of October 28, 2025.

Additional information follows about MSHA references used in the table:

● *Section 104(a) Citations*: The total number of citations received from MSHA under section 104(a) of the Mine Act for alleged violations of health or safety standards that could significantly and substantially contribute to a serious injury if left unabated.

● *Section 104(b) Orders*: The total number of orders issued by MSHA under section 104(b) of the Mine Act, which represents a failure to abate a citation under section 104(a) within the period of time prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

● *Section 104(d) Citations and Orders*: The total number of citations and orders issued by MSHA under section 104(d) of the Mine Act for unwarrantable failure to comply with mandatory health or safety standards.

● *Section 110(b)(2) Violations*: The total number of flagrant violations issued by MSHA under section 110(b)(2) of the Mine Act.

● *Section 107(a) Orders*: The total number of orders issued by MSHA under section 107(a) of the Mine Act for situations in which MSHA determined an imminent danger existed.

Citations and orders can be contested before the Federal Mine Safety and Health Review Commission (the "Commission"), and as part of that process, are often reduced in severity and amount, and are sometimes dismissed. The Commission is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. These cases may involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA, or complaints of discrimination by miners under section 105 of the Mine Act.

------

&nbsp;&nbsp;&nbsp;&nbsp;(1) The definition of a mine under section 3 of the Mine Act includes the mine, as well as other items used in, or to be used in, or resulting from, the work of extracting and processing limestone, such as roads, land, structures, facilities, equipment, machines, tools, kilns, and other property. These other items associated with a single mine have been aggregated in the totals for that mine.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The proposed MSHA assessments issued during the reporting period do not necessarily relate to the citations or orders issued by MSHA during the reporting period or to any pending contests reported above.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Includes any pending legal actions before the Commission involving such mine as of September 30, 2025. Any pending legal actions were initiated by the Company. The pending legal actions may relate to the citations or orders issued by MSHA during the reporting period or to citations or orders issued in prior periods. Due to timing and other factors, the data may not agree with the mine data retrieval system maintained by MSHA. There were no legal actions resolved and two instituted during the reporting period.

**Pattern or Potential Pattern of Violations***.* During the quarter ended September 30, 2025, none of the mines operated by the Company received written notice from MSHA of either (a) a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to mine health or safety hazards under section 104(e) of the Mine Act or (b) the potential to have such a pattern.
