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 (“US GAAP”) 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, 2023. The results of operations for the three- and nine-month periods ended September 30, 2024 are not necessarily indicative of operating results for the full year.

Recent Events. On May 2, 2024, the shareholders of the Company approved an increase in the Company’s number of authorized shares of common stock from 30,000,000 to 45,000,000. On July 12, 2024, the Company effected a 5-for-1 split of its common stock in the form of a stock dividend of four additional shares of common stock for each share outstanding to shareholders of record at the close of business on June 21, 2024 (the “Stock Split”). All share and per share information, including stock-based compensation, throughout this Quarterly Report on Form 10-Q has been retroactively adjusted to reflect the Stock Split. The shares of common stock retain a par value of $0.10 per share. Accordingly, an amount equal to the aggregate par value of the additional shares issued in the Stock Split was reclassified from additional paid-in capital to common stock for all periods presented.

The number and terms of stock-based compensation awards have been adjusted, in order to prevent dilution or enlargement of the rights of participants under the Company’s Amended and Restated 2001 Long-Term Incentive Plan, as Amended and Restated. The fair value of all outstanding awards immediately after the Stock Split did not change when compared to the fair value of such awards immediately prior to the Stock Split. In addition, there was no change to the vesting conditions or classification of any of the awards. No incremental compensation expense was recognized as a result of such adjustments.

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), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), roof shingle manufacturers, oil and gas services, and agriculture (including poultry producers) 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 2024 and 2023 revenues was $12.3 million and $12.2 million, for the respective three-month periods ended September 30, and $34.5 million and $35.4

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

The Company has identified one reportable segment based on the distinctness of the Company’s activities and products: lime and limestone operations. All operations are in the United States. In evaluating the operating results of the Company, management primarily reviews revenues, gross profit, and operating profit from the lime and limestone operations. Operating profit from the Company’s lime and limestone operations includes all of the Company’s selling, general and administrative costs. The Company does not allocate interest income and expense and other expense to its lime and limestone operations. Other identifiable assets include assets related to the Company’s natural gas interests, unallocated corporate assets, and cash items.

Operating results and certain other financial data for the three- and nine-month periods ended September 30, 2024 and 2023 for the Company’s lime and limestone operations segment and other are as follows (in thousands):

The Company paid $0.04 and $0.12 of cash dividends per share of common stock in the three- and nine-month periods ended September 30, 2023, 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):


	September 30,		December 31,
	2024		2023
Lime and limestone inventories:
Raw materials	$	8,808	$	7,834
Finished goods		3,052		3,107
		11,860		10,941
Parts inventories		15,923		13,372
	$	27,783	$	24,313

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, 2024, the Company had no debt outstanding and no draws on the Revolving Facility other than $0.5 million of letters of credit, 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 7 years, with a weighted-average remaining lease term of 4 years at both September 30, 2024 and December 31, 2023. 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.

9. Income Taxes

The Company has estimated that its effective income tax rate for 2024 will be 19.9%. The primary reason for the effective income tax rate being below the federal statutory rate is due to 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

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), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), roof shingle manufacturers, oil and gas services, and agriculture (including poultry producers) 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.

We have identified one reportable segment based on the distinctness of our activities and products: lime and limestone operations. All operations are in the United States. Our other operations consists of natural gas interests through our wholly owned subsidiary, U.S. Lime Company-O&G, LLC. Assets related to our natural gas interests, unallocated corporate assets, and cash items are included in other identified assets. We do not believe that our natural gas interests are material to the current or prior periods.

Our revenues increased 19.4% and 10.2% in the third quarter and first nine months 2024, respectively, compared to the third quarter and first nine months 2023. Revenues from our lime and limestone operations increased 19.6% in the third quarter 2024, compared to the third quarter 2023, due to a 14.2% increase in the average selling prices for our lime and limestone products and a 5.4% increase in sales volumes of our lime and limestone products, which was principally due to increased demand from our construction and roof shingle customers. Revenues from our lime and limestone operations increased 10.3% in the first nine months 2024, compared to the first nine months 2023, due to a 14.3% increase in the average selling prices for our lime and limestone products, partially offset by a 4.0% decrease in sales volumes of our lime and limestone products, principally due to decreased demand from our construction customers, which was partially offset by increased demand from our industrial and roof shingle customers. While overall demand from our construction customers is down for the first nine months 2024, compared to the first nine months 2023, construction demand improved in the third quarter 2024 as weather conditions in the South-Central United States returned to a more normal pattern compared to the heavier than usual rainfalls that we experienced in the first half 2024.

Our gross profit increased 53.1% and 36.9% in the third quarter and first nine months 2024, respectively, compared to the third quarter and first nine months 2023. Gross profit from our lime and limestone operations increased 53.3% and 37.0% in the third quarter and first nine months 2024, respectively, compared to the third quarter and first nine months 2023. The increases in gross profit resulted primarily from the increases in revenues discussed above and decreases in operating expenses, somewhat attributed to lower natural gas prices and optimizing fuel blends on our kilns.

On May 2, 2024, our shareholders approved an increase in the number of authorized shares of our common stock from 30,000,000 to 45,000,000. On July 12, 2024, we effected a 5-for-1 split of our common stock, in the form of a stock dividend of four additional shares of common stock for each share outstanding to shareholders of record at the close of business on June 21, 2024 (the “Stock Split”). All share and per share information, including stock-based compensation, throughout this Quarterly Report on Form 10-Q has been retroactively adjusted to reflect the Stock Split. The shares of common stock retain a par value of $0.10 per share.

Liquidity and Capital Resources.

Net cash provided by operating activities was $87.4 million in the first nine months 2024, compared to $64.7 million in the first nine months 2023, an increase of $22.7 million, or 35.1%. 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 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. In the first nine months 2023, net cash provided by operating activities was principally

composed of $57.5 million net income, $17.8 million DD&A, and $2.4 million stock-based compensation, partially offset by $0.3 million deferred income taxes and a $12.6 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first nine months 2023 included an increase of $10.5 million in trade receivables, net, due primarily to increased sales in the third quarter 2023 compared to the fourth quarter 2022, and an increase of $4.2 million in inventories, partially offset by a decrease of $1.2 million in prepaid expenses and other current assets and an increase of $0.9 in accounts payable and accrued expenses.

We had $16.4 million in capital expenditures in the first nine months 2024, compared to $20.5 million in the first nine months 2023. Net cash used in financing activities was $4.3 million in the first nine months 2024, compared to $3.4 million in the first nine months 2023, consisting primarily of cash dividends paid in each period.

Cash and cash equivalents increased $67.0 million to $255.0 million at September 30, 2024 from $188.0 million at December 31, 2023.

We are not committed to any planned capital expenditures until actual orders are placed for equipment. As of September 30, 2024, we did not have any material commitments for open purchase orders. In September 2024, we received the necessary permit to construct a new vertical kiln at our Texas Lime Company facility. We estimate the construction costs of the new kiln and related equipment and infrastructure will total approximately $65 million. We intend to fund this modernization and development project at our Texas Lime Company facility through cash on hand and cash flows from operations.

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, 2024, we had no debt outstanding and no draws on the Revolving Facility other than $0.5 million of letters of credit, 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 2024 were $89.4 million, compared to $74.9 million in the third quarter 2023, an increase of $14.5 million, or 19.4%. Revenues from our lime and limestone operations were $89.2 million in the third quarter 2024, compared to $74.6 million in the third quarter 2023, an increase of $14.6 million, or 19.6%. The increase in our revenues in the third quarter 2024, compared to the third quarter 2023, resulted from an increase in the average selling prices for our lime and limestone products and increased sales volumes of our lime and limestone products, principally due to increased demand from our construction and roof shingle customers.

For the first nine months 2024, revenues were $237.7 million, compared to $215.6 million in the first nine months 2023, an increase of $22.0 million, or 10.2%. For the first nine months 2024, our lime and limestone revenues were $236.9 million, compared to $214.8 million in the first nine months 2023, an increase of $22.1 million, or 10.3%. The increase in our revenues in the first nine months 2024, compared to the first nine months 2023, resulted from an increase in the average selling prices for our lime and limestone products, partially offset by decreased sales volumes of our lime and limestone products, principally due to decreased demand from our construction customers, offset in part by increased demand from our industrial and roof shingle customers.

Gross profit was $43.1 million in the third quarter 2024, compared to $28.2 million in the third quarter 2023, an increase of $15.0 million, or 53.1%. Gross profit from our lime and limestone operations in the third quarter 2024 was $43.2 million, compared to $28.2 million in the third quarter 2023, an increase of $15.0 million, or 53.3%. The increase in gross profit in the third quarter 2024, compared to the third quarter 2023, resulted primarily from the increased revenues discussed above and a decrease in operating expenses, somewhat attributed to lower natural gas prices and optimizing fuel blends on our kilns.

Gross profit was $108.5 million in the first nine months 2024, compared to $79.3 million in the first nine months 2023, an increase of $29.3 million, or 36.9%. Gross profit from our lime and limestone operations in the first nine months 2024 was $108.7 million, compared to $79.3 million in the first nine months 2023, an increase of $29.4 million, or 37.0%. The increase in gross profit in the first nine months 2024, compared to the first nine months 2023, resulted primarily from the increased revenues discussed above and a decrease in operating expenses, somewhat attributed to lower natural gas prices and optimizing fuel blends on our kilns.

Selling, general and administrative (“SG&A”) expenses were $5.0 million in the third quarter 2024, compared to $4.4 million in the third quarter 2023, an increase of $0.6 million, or 14.3%. SG&A expenses were $14.7 million in the first nine months 2024, compared to $12.8 million in the first nine months 2023, an increase of $1.9 million, or 14.7%. The increases in SG&A expenses in the 2024 periods, compared to the comparable 2023 periods, were primarily due to increased personnel expenses, including stock-based compensation.

Other (income) expense, net was $3.1 million income in the third quarter 2024 and $8.4 million income in the first nine months 2024, compared to $2.2 million income in the third quarter 2023 and $5.5 million income in the first nine months 2023. The increases of $0.9 million and $2.9 million in other (income) expense, net during the 2024 periods, compared to the comparable 2023 periods, were primarily due to interest earned on higher average balances in our cash and cash equivalents.

Income tax expense was $7.8 million and $20.4 million in the third quarter and first nine months 2024, compared to $5.3 million and $14.4 million in the comparable 2023 periods. The increases in income tax expense in the 2024 periods, compared to the comparable 2023 periods, were due to the increases in income before taxes.

Our net income was $33.4 million ($1.16 per share diluted) in the third quarter 2024, compared to net income of $20.7 million ($0.73 per share diluted) in the third quarter 2023, an increase of $12.6 million, or 60.9%. For the first nine months 2024, our net income was $81.8 million ($2.85 per share diluted), compared to $57.5 million ($2.02 per share diluted) in the first nine months 2023, an increase of $24.3 million, or 42.2%.

ITEM 4: 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. OTHER INFORMATION

ITEM 2: 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 2024 pursuant to these provisions or otherwise.

ITEM 4: 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 mine 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, 2024 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.

When a quorum is present at any meeting, the vote of the holders of a majority of the shares entitled to vote, and present in person or represented by proxy, shall be the act of the meeting, unless the vote of a greater number is required by statute, the Restated Articles of Incorporation or these Bylaws, in which case the vote of such greater number shall be requisite to constitute the act of the meeting. The shareholders present or represented at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough shareholders to leave less than a quorum.

Section 7. Voting of Shares. Each outstanding share, regardless of class, shall be entitled to one vote on each matter submitted to a vote at a meeting of the shareholders, except as and to the extent otherwise provided by statute or by the Restated Articles of Incorporation.

No proxy shall be valid after eleven (11) months from the date of its execution unless otherwise provided in the proxy.

Section 2. Number and Qualifications. The Board of Directors shall consist of seven (7) directors, which number may be increased or decreased from time to time by amendment to these Bylaws; provided, however, that at no time shall the number of directors be less than one (1), and no decrease shall have the effect of shortening the term of any incumbent director. None of the directors need be shareholders of the Corporation or residents of the State of Texas.

Section 3. Election and Term of Office. At each annual meeting of the shareholders, the shareholders shall elect directors to hold office until the next succeeding annual meeting. At each election, the persons receiving the greatest number of votes shall be the directors. Each director elected shall hold office for the term for which he is elected and until his successor shall have been duly elected and qualified or until his earlier death, resignation, retirement, disqualification or removal.

Section 4. Removal: Filling of Vacancies. Any or all of the directors may be removed, either for or without cause, at any meeting of the shareholders called expressly for that purpose, by the affirmative vote, in person or by proxy, of the holders of a majority of the shares then entitled to vote in an election of directors. Any vacancy occurring in the Board of Directors, resulting from the death, resignation, retirement, disqualification or removal from office of any director, or otherwise than as the result of an increase in the number of directors, may be filled by the affirmative vote of a majority of the remaining directors, though less than a quorum of the Board, or may be filled by election at any annual or special meeting of the shareholders called for that purpose. A director elected to fill a vacancy shall be elected for the unexpired term of his predecessor in office. A directorship to be filled by reason of any increase in the number of directors may be filled by the Board of Directors for a term of office continuing only until the next election of one (1) or more directors by the shareholders, or may be filled by election at any annual or specia1 meeting of the shareholders called for that purpose; provided, however, that the Board of Directors may not fill more than two (2) such directorships during the period between any two (2) successive annual meetings of shareholders.

Section 7. Regular Meetings. Regular meetings of the Board of Directors, of which no notice shall be necessary, shall be held at such times and places as may be fixed from time to time by resolution adopted by the Board and communicated to all directors. Except as otherwise provided by statute, the Restated Articles of Incorporation or these Bylaws, any and all business may be transacted at any regular meeting.

Section 8. Special Meetings. Special meetings of the Board of Directors may be called by the Chairman of the Board or the President on twenty-four (24) hours’ notice to each director, either personally or by mail or by email or fax. Special meetings shall be called by the President or the Secretary in like manner and on like notice on the written request of two (2) directors. Except as may be otherwise expressly provided by statute, the Restated Articles of Incorporation or these Bylaws, neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Board of Directors need be specified in the notice or waiver of notice of such meeting.

Section 9. Quorum and Manner of Acting. At all meetings of the Board of Directors the presence of a majority of the number of directors fixed by or in the manner provided by these Bylaws shall be necessary and sufficient to constitute a quorum for the transaction of business, except as otherwise provided by statute, the Restated Articles of Incorporation or these Bylaws. The act of a majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors, unless the act of a greater number is required by statute, the Restated Articles of Incorporation or these Bylaws, in which case the act of such greater number shall be requisite to constitute the act of the Board. If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present. At any such adjourned meeting, any business may be transacted that might have been transacted at the meeting as originally convened.

Section 10. Action Without a Meeting. Unless otherwise restricted by the Restated Articles of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting, if all members of the Board or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board or committee. An electronic transmission by a director, consenting to an action to be taken and transmitted by a director, is considered written, signed and dated if the transmission sets forth or is delivered with information from which the Corporation can determine that the transmission was transmitted by the director and the date on which the director transmitted the transmission.

Section 11. Telephone Meetings. Subject to the provisions of any statute and these Bylaws regarding notice of meetings, members of the Board of Directors or members of any committee designated by the Board may, unless

otherwise restricted by the Restated Articles of Incorporation or these Bylaws, participate in and hold a meeting of the Board or committee by using conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in a meeting pursuant to this section shall constitute presence in person at such meeting, except when a person participates in the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting was not lawfully called or convened.

Section 12. Interested Directors and Officers. No contract or transaction between the Corporation and one (1) or more of its directors or officers or between the Corporation and any other Corporation, partnership, association, or other organization in which one (1) or more of its directors or officers are directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the Board of Directors or committee thereof which authorizes the contract or transaction, or solely because his or their votes are counted for such purpose, if: (i) the material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the Board or committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative vote of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; (ii) the material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the shareholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the shareholders; or (iii) the contract or transaction is fair as to the Corporation as of the time it is authorized, approved or ratified by the Board, a committee thereof or the shareholders. Common or interested directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee which authorizes the contract or transaction.

Section 13. Directors’ Compensation. The Board of Directors shall have authority to determine, from time to time, the amount of compensation, if any, which shall be paid to its members for their services as directors and as members of standing or special committees. The Board of Directors shall also have power in its discretion to provide for and to pay to directors rendering services to the Corporation not ordinarily rendered by directors as such, special compensation appropriate to the value of such services as determined by the Board from time to time. Nothing herein contained shall be construed to preclude any director from serving the Corporation in any other capacity and receiving compensation therefor.

Section 14. Advisory Directors. The Board of Directors may appoint such number of advisory directors as it shall from time to time determine. Each advisory director appointed shall hold office for the term for which he is elected or until his earlier death, resignation, retirement or removal by the Board. The advisory directors may attend and be present at the meetings of the Board, although a meeting of the Board may be held without notice to the advisory directors and the advisory directors shall not be considered in determining whether a quorum of the Board is present. The advisory directors shall advise and counsel the Board of Directors on the business and operations of the Corporation as requested by the Board; provided however, that the advisory directors shall not be entitled to vote on any matter presented to the Board.

Section 15. Directors Emeritus. The Board of Directors may appoint directors emeritus as provided in Article Three Section 14 hereof. All regular directors who have served as such for not less than ten (10) successive years at the time of the annual meeting of the shareholders next succeeding their retirement shall be eligible to be appointed as a director emeritus to serve until his death, resignation, retirement or removal by the Board. Directors emeritus shall be considered as advisory directors.

Whenever under the provisions of any statute, the Restated Articles of Incorporation or these Bylaws, notice is required to be given to any committee member, director or shareholder of the Corporation, and no provision is made as to how such notice shall be given, it shall not be construed to mean personal notice, but any such notice may be given in writing by mail, postage prepaid, or reliable overnight or same-day courier, addressed to such member, director or shareholder at his address as it appears on the records or (in the case of a shareholder) the stock transfer books of the Corporation, or by any mode of electronic transmission consented to by such member, director or shareholder.

Whenever any notice is required to be given to any committee member, director or shareholder of the Corporation by any statute, the Restated Articles of Incorporation or these Bylaws, a waiver thereof in writing signed by the person or persons entitled to such notice, whether before or after the time

stated therein, shall be deemed equivalent to the giving of such notice. Attendance of a director at a meeting of the Board of Directors or a committee shall constitute a waiver of notice of such meeting, except where a director attends the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

Section 3. When Notice Not Required. Any notice required to be given to any shareholder by statute, the Restated Articles of Incorporation or these Bylaws need not be given to the shareholder if: (i) notice of two (2) consecutive annual meetings and all notices of meetings held during the period between those annual meetings, if any, or (ii) all but in no event less than two (2) payments (if sent by first class mail) of distributions or interest on securities during a twelve (12)-month period have been mailed to that person, addressed at his address as shown on the records of the Corporation, and have been returned undeliverable. Any action or meeting taken or held without notice to such a person shall have the same force and effect as if the notice had been duly given and, if the action taken by the Corporation is reflected in any articles or document filed with the Secretary of State, those articles or that document may state that notice was duly given to all persons to whom notice was required to be given. If such a person delivers to the Corporation a written notice setting forth his then-current address, the requirement that notice be given to that person shall be reinstated.

proceeding, had no reasonable cause to believe that his conduct was unlawful; provided, however, that, if the person is found liable to the Corporation or is found liable on the basis that a personal benefit was improperly received by the person, the indemnification shall be limited to reasonable expenses actually incurred by the person in connection with the proceeding and shall not be made in respect of any proceeding in which the person shall have been found liable for willful or intentional misconduct in the performance of his duty to the Corporation.

The determinations required above that the person has satisfied the prescribed conduct and belief standards must be made (a) by a majority vote of a quorum consisting of directors who at the time of the vote are not named defendants or respondents in the proceeding, (b) if such a quorum cannot be obtained, by a majority vote of a committee of the Board of Directors, designated to act in the matter by a majority vote of all directors, consisting solely of two (2) or more directors who at the time of the vote are not named defendants or respondents in the proceeding, (c) by special legal counsel selected by the Board or a committee of the Board by vote as set forth in clause (a) or (b) of this sentence, or, if such a quorum cannot be obtained and such a committee cannot be established, by a majority vote of all directors, or (d) by the shareholders in a vote that excludes the shares held by directors who are named defendants or respondents in the proceeding. The determination as to reasonableness of expenses must be made in the same manner as the determination that the person has satisfied the prescribed conduct and belief standards, except that, if the determination that the person has satisfied the prescribed conduct and belief standards is made by special legal counsel, the determination as to reasonableness of expenses must be made by the Board of Directors or a committee of the Board by vote as set forth in clause (a) or (b) of the immediately preceding sentence or, if such a quorum cannot be obtained and such a committee cannot be established, by a majority vote of all directors.

The termination of a proceeding by judgment, order, settlement or conviction, or on a plea of nolo contendere or its equivalent is not of itself determinative that the person did not meet the requirements for indemnification set forth above. A person shall be deemed to have been found liable in respect of any claim, issue or matter only after the person shall have been so adjudged by a court of competent jurisdiction after exhaustion of all appeals therefrom.

Notwithstanding any other provision of these Bylaws, the Corporation shall pay or reimburse expenses incurred by a director in connection with his appearance as a witness or other participation in a proceeding at a time when he is not a named defendant or respondent in the proceeding.

Section 2. Advancement of Expenses to Directors. Reasonable expenses incurred by a director who was, is, or is threatened to be made, a named defendant or respondent in a proceeding, or incurred by a director in connection with his appearance as a witness or other participation in a proceeding at a time when he is not a named defendant or respondent in the proceeding, shall be paid or reimbursed by the Corporation, in advance of the final disposition of the proceeding and without any of the determinations specified in Section 1 of this Article, after the Corporation receives a written affirmation by the director of his good faith belief that he has met the standard of conduct necessary for indemnification under Section 1 of this Article and a written undertaking by or on behalf of such director to repay the amount paid or reimbursed if it is ultimately determined that he has not met those requirements. The written undertaking described in the immediately preceding sentence to repay the amount paid or reimbursed to the director by the Corporation must be an unlimited general obligation of the director but need not be secured and it may be accepted without reference to financial ability to make repayment.

Section 3. Officers. The Corporation shall indemnify and advance expenses to an officer of the Corporation to the same extent that it is required to indemnify and advance expenses to directors under these Bylaws or by statute. In addition, the Corporation may indemnify and advance expenses to an officer of the Corporation to such further extent, consistent with statute, as may be provided by the Restated Articles of Incorporation, these Bylaws, general or specific action of the Board of Directors, or contract or as permitted or required by common law.

Section 4. Others. The Corporation may indemnify and advance expenses to an employee or agent of the Corporation to the same extent that it is required to indemnify and advance expenses to directors under these Bylaws or by statute. The Corporation may indemnify and advance expenses to persons who are not or were not officers, employees or agents of the Corporation but who are or were serving at the request of the Corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of another Corporation for profit subject to the provisions of the Texas Business Organizations Code, Corporation for profit organized under laws other than the laws of the State of Texas, partnership, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise to the same extent that it is required to indemnify and advance expenses to directors under this Article or by statute. The Corporation may indemnify and advance expenses to an employee, agent or other person serving at the request of the Corporation (as described above in this Section 4) who is not a director to such further

extent, consistent with statute, as may be provided by the Restated Articles of Incorporation, these Bylaws, general or specific action of the Board of Directors, or contract or as permitted or required by common law.

Section 5. Insurance and Other Arrangements. The Corporation may purchase and maintain insurance or establish and maintain other arrangements on behalf of any person who is or was a director, officer, employee or agent of the Corporation or who is or was serving at the request of the Corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of another Corporation for profit subject to the provisions of the Texas Business Organizations Code, Corporation for profit organized under laws other than the laws of the State of Texas, partnership, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise, against or in respect of any liability asserted against him and incurred by him in such a capacity or arising out of his status as such a person, whether or not the Corporation would have the power to indemnify him against that liability by statute or under these Bylaws. If the insurance or other arrangement is with a person or entity that is not regularly engaged in the business of providing insurance coverage, the insurance or other arrangement may provide for payment of a liability with respect to which the Corporation would not have the power to indemnify the person only if including coverage for the additional liability has been approved by the shareholders of the Corporation.

Without limiting the power of the Corporation to purchase, procure, establish or maintain any kind of insurance or other arrangement, the Corporation may, for the benefit of persons indemnified by the Corporation, (i) create a trust fund; (ii) establish any form of self-insurance; (iii) secure its indemnity obligation by grant of a security interest or other lien on the assets of the Corporation; or (iv) establish a letter of credit, guaranty or surety arrangement. The insurance or other arrangement may be purchased, procured, maintained or established within the Corporation or with any insurer or other person deemed appropriate by the Board of Directors regardless of whether all or part of the stock or other securities of the insurer or other person are owned in whole or part by the Corporation. In the absence of fraud, the judgment of the Board of Directors as to the terms and conditions of the insurance or other arrangement and the identity of the insurer or other person participating in an arrangement shall be conclusive and the insurance or other arrangement shall not be voidable, and shall not subject the directors approving the insurance or other arrangement to liability, on any ground, regardless of whether directors participating in the approval are beneficiaries of the insurance or other arrangement.

Section 6. Report to Shareholders. Any indemnification of or advance of expenses to a director in accordance with this Article or the provisions of any statute shall be reported in writing to the shareholders with or before the notice or waiver of notice of the next shareholders’ meeting or with or before the next submission to shareholders of a consent to action without a meeting and, in any case, within the twelve (12)-month period immediately following the date of the indemnification or advance.

Section 7. Entitlement. These indemnification provisions shall inure to each of the directors, officers, employees and agents of the Corporation, and other persons serving at the request of the Corporation (as provided in this Article), whether or not the claim asserted against him is based on matters that antedate the adoption of this Article, and in the event of his death shall extend to his legal representatives; but such rights shall not be exclusive of any other rights to which he may be entitled.

Section 8. Definitions. For purposes of this Article:

(a) The term “expenses” includes court costs and attorneys’ fees;

(b) The term “proceeding” means any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative, any appeal in such an action, suit or proceeding, and any inquiry or investigation that could lead to such an action, suit or proceeding;

(c) The term “director” means any person who is or was a director of the Corporation and any person who, while a director of the Corporation, is or was serving at the request of the Corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of another Corporation for profit subject to the provisions of the Texas Business Organizations Code, Corporation for profit organized under laws other than the laws of the State of Texas, partnership, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise;

(d) The term “corporation” includes any domestic or foreign predecessor entity of the Corporation in a merger, consolidation or other transaction in which the liabilities of the predecessor are transferred to the Corporation by operation of law and in any other transaction in which the Corporation assumes the liabilities of the predecessor but does not specifically exclude liabilities that are the subject matter of this Article;

(e) The term “official capacity” means, when used with respect to a director, the office of director in the Corporation and, when used with respect to a person other than a director, the elective or appointive office in the

Corporation held by the officer or the employment or agency relationship undertaken by the employee or agent on behalf of the Corporation, but does not include service for any other Corporation for profit subject to the provisions of the Texas Business Organizations Code or Corporation for profit organized under laws other than the laws of the State of Texas or any partnership, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise; and

(f) The Corporation is deemed to have requested a director to serve an employee benefit plan whenever the performance by him of his duties to the Corporation also imposes duties on or otherwise involves services by him to the plan or participants or beneficiaries of the plan. Excise taxes assessed on a director with respect to an employee benefit plan pursuant to applicable law are deemed fines. Action taken or omitted to be taken by a director with respect to an employee benefit plan in the performance of his duties for a purpose reasonably believed by him to be in the interest of the participants and beneficiaries of the plan is deemed to be for a purpose which is not opposed to the best interests of the Corporation.

Section 9. Severability. The provisions of this Article are intended to comply with Title 1. Chapter 8. Subchapters B. and C. of the Texas Business Organizations Code. To the extent that any provision of this Article authorizes or requires indemnification or the advancement of expenses contrary to such statute or the Restated Articles of Incorporation, the Corporation’s power to indemnify or advance expenses under such provision shall be limited to that permitted by such statute and the Restated Articles of Incorporation and any limitation required by such statute or the Restated Articles of Incorporation shall not affect the validity of any other provision of this Article.

ARTICLE TEN

MISCELLANEOUS

Section 1. Distributions and Share Dividends. Distributions in the form of dividends and share dividends on the outstanding shares of the Corporation, subject to any restrictions in the Restated Articles of Incorporation and to the limitations imposed by statute, may be declared by the Board of Directors at any regular or special meeting. Distributions in the form of dividends may be declared and paid in cash, in property, or in evidences of the Corporation’s indebtedness, or in any combination thereof, and may be declared and paid in combination with share dividends. Distributions of cash or property (tangible or intangible) made or payable by the Corporation, whether in liquidation or from earnings, profits, assets or capital, including all distributions that were payable but not paid to the registered owner of the shares, his heirs, successors or assigns but that are now being held in suspense by the Corporation or that were paid or delivered by it into an escrow account or to a trustee or custodian, shall be payable by the Corporation, escrow agent, trustee or custodian to the person registered as owner of the shares in the Corporation’s stock transfer books as of the record date determined for the distribution, his heirs, successors or assigns. The person in whose name the shares are or were registered in the stock transfer books of the Corporation as of the record date shall be deemed to be the owner of the shares registered in his name at that time.

Section 2. Reserves. The Corporation may, by resolution of the Board of Directors, create a reserve or reserves out of its surplus or designate or allocate any part or all of its surplus in any manner for any proper purpose or purposes, and may increase, decrease or abolish any such reserve, designation or allocation in the same manner.

Section 3. Signature of Negotiable Instruments. All bills, notes, checks or other instruments for the payment of money shall be signed or countersigned by such officer, officers, agent or agents, and in such manner, as are permitted by these Bylaws and as from time to time may be prescribed by resolution (whether general or special) of the Board of Directors or the Executive Committee.

Section 4. Fiscal Year. The fiscal year of the Corporation shall be fixed by resolution of the Board of Directors.

Section 5. Seal. The seal of the Corporation shall be in such form as shall be adopted and approved from time to time by the Board of Directors. The seal may be used by causing it, or a facsimile thereof, to be impressed, affixed, imprinted or in any manner reproduced.

Section 6. Loans and Guaranties. The Corporation may lend money to, guaranty obligations of and otherwise assist its directors, officers and employees if the Board of Directors determines that such a loan, guaranty or assistance reasonably may be expected to benefit, directly or indirectly, the Corporation and is consistent with applicable law and other requirements.

Section 7. Closing of Transfer Books and Record Date. For the purpose of determining shareholders entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof, or entitled to receive a distribution

by the Corporation (other than a distribution involving a purchase or redemption by the Corporation of any of its own shares) or a share dividend, or in order to make a determination of shareholders for any other proper purpose, the Board of Directors may provide that the stock transfer books of the Corporation shall be closed for a stated period not to exceed, in any case, sixty (60) days. If the stock transfer books shall be closed for the purpose of determining shareholders entitled to notice of or to vote at a meeting of shareholders, such books shall be closed for at least ten (10) days immediately preceding such meeting. In lieu of closing the stock transfer books, the Board of Directors may fix in advance a date as the record date for any such determination of shareholders, such date in any case not to be more than sixty (60) days and, in case of a meeting of shareholders, not less than ten (10) days prior to the date on which the particular action requiring such determination of shareholders is to be taken. If the stock transfer books are not closed and no record date is fixed for the determination of shareholders entitled to notice of or to vote at a meeting of shareholders, or entitled to receive a distribution (other than a distribution involving a purchase or redemption by the Corporation of any of its own shares) or a share dividend, the date on which notice of the meeting is mailed, sent, or transmitted as provided by these Bylaws, or the date on which the resolution of the Board of Directors declaring such distribution or share dividend is adopted, as the case may be, shall be the record date for such determination of shareholders. The record date for determining shareholders entitled to call a special meeting is the date the first shareholder signs the notice of that meeting. When a determination of shareholders entitled to vote at any meeting has been made as provided in this Section, such determination shall apply to any adjournment thereof except where the determination has been made through the closing of the stock transfer books and the stated period of closing has expired.

Section 8. Surety Bonds. Such officers and agents of the Corporation (if any) as the Board of Directors may direct from time to time shall be bonded for the faithful performance of their duties and for the restoration to the Corporation, in case of their death, resignation, retirement, disqualification or removal from office, of all books, papers, vouchers, money and other property of whatever kind in their possession or under their control belonging to the Corporation, in such amounts and by such surety companies as the Board may determine. The premiums on such bonds shall be paid by the Corporation, and the bonds so furnished shall be in the custody of the Secretary.

Section 9. Gender. Words of any gender used in these Bylaws shall be construed to include each other gender, unless the context requires otherwise.

ARTICLE ELEVEN

AMENDMENTS

These Bylaws may be amended or repealed, or new bylaws may be adopted, by the affirmative vote of a majority of the directors present at any meeting of the Board of Directors at which a quorum is present or by unanimous written consent of all the directors, unless (i) by statute or the Restated Articles of Incorporation the power is reserved exclusively to the shareholders in whole or in part, or (ii) the shareholders in amending, repealing or adopting a particular bylaw expressly provide that the Board may not amend or repeal that bylaw. Unless the Restated Articles of Incorporation or a bylaw adopted by the shareholders provides otherwise as to all or some portion of the Bylaws, the shareholders may amend, repeal or adopt the Bylaws even though the Bylaws may also be amended, repealed or adopted by the Board of Directors.

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, 2024, and all pending legal actions as of June 30, 2024. 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, 2024 were taken from the MSHA system as of October 29, 2024.

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.

(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.

(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.

(3)

Includes any pending legal actions before the Commission involving such mine as of September 30, 2024. 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 or instituted during the reporting period.

Pattern or Potential Pattern of Violations. During the quarter ended September 30, 2024, 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.

Accounting Policies (Policies)	Sep. 30, 2024
Accounting Policies
Revenue Recognition	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 2024 and 2023 revenues was $12.3 million and $12.2 million, for the respective three-month periods ended September 30, and $34.5 million and $35.4 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	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.
