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, comprehensive income 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, 2021. The results of operations for the three- and nine-month periods ended September 30, 2022 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), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), roof shingle manufacturers, agriculture (including poultry and cattle feed 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 (“Mill Creek”), 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.

On February 9, 2022, the Company acquired 100% of the equity interest of Mill Creek, a dolomite mining and production company located in Mill Creek, Oklahoma, for $5.6 million cash. Upon acquisition, Mill Creek’s assets and liabilities were recorded at fair value with $5.4 million of the purchase price allocated to property, plant, and equipment. Mill Creek contributed $1.3 million and $3.1 million to the Company’s revenues for the three- and nine-months ended September 30, 2022, respectively. The Company believes this acquisition will complement its existing geographic footprint.

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 2022 and 2021 revenues was $12.3 million and $9.5 million, for the respective three-month periods ended September 30, and $34.0 million and $26.0 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.

Accounts Receivable. 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. 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

7

receivables. Due to the relatively homogenous nature of its trade receivables, the Company does not believe there is any meaningful asset-specific differences within its accounts receivable 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.

Leases. The Company determines if an arrangement is a lease at inception. When recording operating leases, the Company records a lease liability based on the net present value of the lease payments over the lease term, using the interest rate implicit in the lease, if known, or an incremental rate on a collateralized basis over a similar term and amount to the lease, and a corresponding right-of-use asset. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liabilities and operating lease liabilities, excluding current portion, on the condensed consolidated balance sheets. Lease expense is recognized over the lease term on a straight-line basis. Lease terms include options to extend the lease when it is reasonably certain the Company will exercise the option. For leases with a term of twelve months or less, the Company does not record a right-of-use asset and a lease liability and records lease expense on a straight-line basis. See Note 8 to the condensed consolidated financial statements.

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 within a single region 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. Depreciation, depletion and amortization in the table below include only amounts that are included in cost of revenues in the Company’s condensed consolidated statements of 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 expense and interest and other income (expense), net to its lime and limestone operations. Other revenues, gross profit and operating profit in the Company’s segment disclosures include the Company’s natural gas interests. Other identifiable assets include assets related to the Company’s natural gas interests, unallocated corporate assets and cash items.

The following table sets forth operating results and certain other financial data for the Company’s lime and limestone operations segment and other (in thousands):

5. Income and Dividends Per Share of Common Stock

At September 30, 2022, the Company had 30,000,000 shares of common stock authorized and 5,673,574 shares outstanding.

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

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
Net income for basic and diluted income per common share	$	15,726	$	11,308	$	34,632	$	29,432
Weighted-average shares for basic income per common share		5,674		5,658		5,671		5,656
Effect of dilutive securities:
Employee and director stock options(1)		6		13		8		12
Adjusted weighted-average shares and assumed exercises for diluted income per common share		5,680		5,671		5,679		5,668
Basic net income per common share	$	2.77	$	2.00	$	6.11	$	5.20
Diluted net income per common share	$	2.77	$	1.99	$	6.10	$	5.19

(1) Excludes 20 and 16 stock options for the three- and nine-month periods ended September 30, 2022, respectively, as anti-dilutive because the exercise price exceeded the average per share market price for the period. No stock options were excluded for the three- and nine-month periods ended September 30, 2021 as anti-dilutive.

9

The Company paid $0.20 and $0.60 of cash dividends per share of common stock in the three- and nine-month periods ended September 30, 2022, respectively. The Company paid $0.16 and $0.48 of cash dividends per share of common stock in the three- and nine-month periods ended September 30, 2021, respectively.

6. Inventories, Net

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, net consisted of the following (in thousands):

	September 30,		December 31,
	2022		2021
Lime and limestone inventories:
Raw materials	$	4,361	$	3,232
Finished goods		2,391		2,677
		6,752		5,909
Service parts inventories		10,900		9,207
	$	17,652	$	15,116

7. Banking Facilities and Debt

The Company’s credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 2019 and November 21, 2019, 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 May 2, 2024.

Interest rates on the Revolving Facility are, at the Company’s option, LIBOR (or a replacement rate as determined by the Lender and the Company) 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 0.200% 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, 2022, the Company had no debt outstanding and no draws on the Revolving Facility other than $0.3 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 1 to 6 years, with a weighted-average remaining lease term of 4 years at each of September 30, 2022 and December 31, 2021. Some operating leases include options to extend the leases for up to 5 years.

10

The components of lease costs for the three and nine months ended September 30, 2022 and 2021 were as follows (in thousands):

		Three Months Ended September 30,				Nine Months Ended September 30,
	Classification	2022		2021		2022		2021
Operating lease costs(1)	Cost of revenues	$	606	$	444	$	1,746	$	1,279

Supplemental cash flow information pertaining to the Company’s leasing activity for the nine months ended September 30, 2022 and 2021 is as follows (in thousands):

	Nine Months Ended September 30,
	2022		2021
Cash payments for operating lease liabilities	$	1,065	$	1,059
Right-of-use assets obtained in exchange for operating lease obligations	$	1,767	$	1,545

9. Income Taxes

The Company has estimated that its effective income tax rate for 2022 will be 19.7%. 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

On September 16, 2022, the Company paid $1.1 million in cash dividends based on a dividend of $0.20 per share of its common stock, to shareholders of record at the close of business on August 26, 2022. On June 17, 2022, the Company paid $1.1 million in cash dividends based on a dividend of $0.20 per share of its common stock, to shareholders of record at the close of business on May 27, 2022. On March 18, 2022, the Company paid $1.1 million in

11

cash dividends, based on a dividend of $0.20 per share of its common stock, to shareholders of record at the close of business on February 25, 2022.

11. Subsequent Event

On October 26, 2022, the Company’s Board of Directors declared a regular quarterly cash dividend of $0.20 per share on the Company’s common stock. This dividend is payable on December 16, 2022, to shareholders of record at the close of business on November 25, 2022.

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, agriculture (including poultry and cattle feed 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 (“Mill Creek”), 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 within a single geographic region in the United States.

In addition to our lime and limestone operations, we hold natural gas interests through our wholly owned subsidiary, U.S. Lime Company – O&G, LLC. The revenues, gross profit and operating profit from our natural gas interests are included in Other for our reportable segment disclosures. 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.

On February 9, 2022, we acquired 100% of the equity interest of Mill Creek, a dolomite mining and production company located in Mill Creek, Oklahoma, for $5.6 million cash. Upon acquisition, Mill Creek’s assets and liabilities were recorded at fair value, with $5.4 million of the purchase price allocated to property, plant, and equipment. Mill Creek contributed $1.3 million and $3.1 million to our revenues for the three- and nine-months ended September 30, 2022, respectively. We believe that this acquisition will complement our existing geographic footprint.

Our revenues increased 27.0% and 24.2% in the third quarter and first nine months 2022, respectively, compared to the third quarter and first nine months 2021. The increase in our revenues in the third quarter 2022, compared to the third quarter 2021, resulted primarily from a 14.7% increase in the average selling prices for our lime and limestone products and a 12.3% increase in sales volumes of our lime and limestone products, principally due to increased demand from our construction, agriculture, roofing, and oil and gas services customers. The increase in our revenues in the first nine months 2022, compared to the first nine months 2021, resulted primarily from an 11.7% increase in sales volumes of our lime and limestone products, principally due to increased demand from our construction, agriculture, and oil and gas services customers, and a 7.4% increase in the average selling prices for our lime and limestone products.

Our gross profit increased 30.3% in the third quarter 2022 and 16.5% in the first nine months 2022, compared to the third quarter and first nine months 2021. The increases in gross profit in the third quarter and first nine months 2022, compared to the comparable 2021 periods, resulted primarily from the increased revenues discussed above, partially offset by increased lime and limestone production costs, principally from higher transportation, energy, labor, and supplies costs. The pace of increases in production costs slowed during the third quarter 2022, relative to the inflation of the first half of the year. However, risks to our production costs, supply chain, and freight and transportation are still present. These risks include, but are not limited to, the impact foreign oil production cuts may have on the price of petroleum and petroleum-based products, and the risk potential railroad labor disruptions pose to our supply chain.

In the third quarter 2022, the strong demand from our construction customers benefited from long stretches of dry weather in the Texas markets. Increases in the average selling price of our lime and limestone products in the third quarter 2022 helped pass along the cost increases that we have experienced during the year.

Liquidity and Capital Resources.

Net cash provided by operating activities was $43.9 million in the first nine months 2022, compared to $44.1 million in the first nine months 2021, a decrease of $0.2 million, or 0.5%. 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 2022, net cash provided by operating activities was principally composed of $34.6 million net income, $16.5 million DD&A, $2.2 million deferred income taxes, $1.9 million stock-based compensation, and a $11.1 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first nine months 2022

14

included an increase of $12.4 million in trade receivables, net, due primarily to increased sales in the third quarter 2022 compared to the fourth quarter 2021, an increase of $2.4 million in inventories, a $2.5 million increase in accounts payable and accrued expenses, and a decrease of $1.1 million in prepaid expenses and other current assets. In the first nine months 2021, net cash provided by operating activities was principally composed of $29.4 million net income, $15.6 million DD&A, $2.0 million deferred income taxes, $1.7 million stock-based compensation, and a $4.7 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first nine months 2021 included an increase of $6.3 million in trade receivables, net, due primarily from increased sales in the third quarter 2021 compared to the fourth quarter 2020, a decrease of $0.8 million in prepaid and other assets, and a decrease of $0.5 million in inventories.

We had $23.8 million in capital expenditures in the first nine months 2022, including $5.6 million for the acquisition of Mill Creek, compared to $23.7 million in the first nine months 2021. In the first nine months 2022, we experienced increased costs associated with our normal recurring capital and re-equipping projects at our plants and other facilities, as part of the current overall inflationary environment. We expect that the increase in these capital costs will result in increased DD&A expense in future periods. Net cash used in financing activities was $3.4 million in the first nine months 2022, compared to $2.7 million in the first nine months 2021, consisting primarily of cash dividends paid in each period.

Cash and cash equivalents increased $17.3 million to $122.7 million at September 30, 2022 from $105.4 million at December 31, 2021.

We are not committed to any planned capital expenditures until actual orders are placed for equipment. As of September 30, 2022, we did not have any material commitments for open purchase orders.

Our credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 2019 and November 21, 2019, 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 May 2, 2024.

Interest rates on the Revolving Facility are, at our option, LIBOR (or a replacement rate as determined by the Lender and the Company) 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 0.200% 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, 2022, we had no debt outstanding and no draws on the Revolving Facility other than $0.3 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 2022 were $66.5 million, compared to $52.3 million in the third quarter 2021, an increase of $14.1 million, or 27.0%. For the first nine months 2022, revenues were $177.9 million, compared to $143.1 million in the first nine months 2021, an increase of $34.7 million, or 24.2%. Revenues from our lime and limestone

15

operations were $65.7 million in the third quarter 2022, compared to $51.7 million in the third quarter 2021, an increase of $14.0 million, or 27.0%. For the first nine months 2022, lime and limestone revenues were $175.6 million, compared to $141.8 million in the first nine months 2021, an increase of $33.8 million, or 23.8%. The increase in our revenues in the third quarter 2022, compared to the third quarter 2021, resulted primarily from an increase in sales volumes of our lime and limestone products, principally due to increased demand from our construction, agriculture, roofing, and oil and gas services customers, as well as an increase in the average selling prices for our lime and limestone products. The increase in our revenues in the first nine months 2022, compared to the first nine months 2021, resulted primarily from an increase in sales volumes of our lime and limestone products, principally due to increased demand from our construction, agriculture, and oil and gas services customers, and an increase in the average selling prices for our lime and limestone products.

Gross profit was $22.6 million in the third quarter 2022, compared to $17.3 million in the third quarter 2021, an increase of $5.2 million, or 30.3%. Gross profit from our lime and limestone operations in the third quarter 2022 was $22.2 million, compared to $17.1 million in the third quarter 2021, an increase of $5.0 million, or 29.4%. Gross profit was $53.5 million in the first nine months 2022, compared to $45.9 million in the first nine months 2021, an increase of $7.6 million, or 16.5%. Gross profit from our lime and limestone operations in the first nine months 2022 was $52.3 million, compared to $45.6 million in the first nine months 2021, an increase of $6.7 million or 14.7%. The increases in lime and limestone gross profit in the third quarter and first nine months 2022, compared to the comparable 2021 periods, resulted primarily from the increased revenues discussed above, partially offset by increased production costs, principally from higher transportation, energy, labor, and supplies costs.

Selling, general and administrative (“SG&A”) expenses were $3.6 million in the third quarter 2022, compared to $3.1 million in the third quarter 2021, an increase of $0.4 million, or 12.7%. SG&A expenses were $11.0 million in the first nine months 2022, compared to $9.2 million in the first nine months 2021, an increase of $1.9 million, or 20.3%. The increases in SG&A expenses in the 2022 periods were primarily due to increased personnel expense, including stock compensation.

Interest expense was $64 thousand and $190 thousand in the third quarter and first nine months 2022, respectively, compared to $63 thousand and $187 thousand in the comparable 2021 periods. We had no outstanding debt during any of the periods. Interest and other income, net was $578 thousand and $815 thousand in the third quarter and first nine months 2022, respectively, compared to $147 thousand and $272 thousand in the comparable 2021 periods. The increase in interest and other income, net during the third quarter and first nine months 2022, compared to the comparable 2021 periods, was due to higher interest rates on higher average balances in our cash and cash equivalents.

Income tax expense was $3.8 million and $8.5 million in the third quarter and first nine months 2022, respectively, compared to $3.0 million and $7.4 million in the comparable 2021 periods. Our effective income tax rate was reduced from the federal rate primarily 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.

Our net income was $15.7 million ($2.77 per share diluted) in the third period 2022, compared to net income of $11.3 million ($1.99 per share diluted) in the third period 2021, an increase of $4.4 million, or 39.1%. For the first nine months 2022, our net income was $34.6 million ($6.10 per share diluted), compared to $29.4 million ($5.19 per share diluted) in the first nine months 2021, an increase of $5.2 million, or 17.7%.

ITEM 3:     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk.

We could be exposed to changes in interest rates, primarily as a result of floating interest rates on the Revolving Facility. There was no outstanding balance on the Revolving Facility subject to interest rate risk at September 30, 2022. Any future borrowings under the Revolving Facility would be subject to interest rate risk. See Note 7 of Notes to Condensed Consolidated Financial Statements.

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 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 2022 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, 2022 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.

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, 2022 and all pending legal actions as of September 30, 2022. 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, 2022 were taken from the MSHA system as of October 25, 2022.

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, 2022. 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 was 1 legal action resolved and 2 legal actions instituted during the reporting period.

Pattern or Potential Pattern of Violations. During the quarter ended September 30, 2022, 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.

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, agriculture (including poultry and cattle feed 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 (“Mill Creek”), 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.

On February 9, 2022, the Company acquired 100% of the equity interest of Mill Creek, a dolomite mining and production company located in Mill Creek, Oklahoma, for $5.6 million cash. Upon acquisition, Mill Creek’s assets and liabilities were recorded at fair value with $5.4 million of the purchase price allocated to property, plant, and equipment. Mill Creek contributed $1.3 million and $3.1 million to the Company’s revenues for the three- and nine-months ended September 30, 2022, respectively. The Company believes this acquisition will complement its existing geographic footprint.

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 2022 and 2021 revenues was $12.3 million and $9.5 million, for the respective three-month periods ended September 30, and $34.0 million and $26.0 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.

Accounts Receivable. 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. 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 is any meaningful asset-specific differences within its accounts receivable 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.

Leases. The Company determines if an arrangement is a lease at inception. When recording operating leases, the Company records a lease liability based on the net present value of the lease payments over the lease term, using the interest rate implicit in the lease, if known, or an incremental rate on a collateralized basis over a similar term and amount to the lease, and a corresponding right-of-use asset. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liabilities and operating lease liabilities, excluding current portion, on the condensed consolidated balance sheets. Lease expense is recognized over the lease term on a straight-line basis. Lease terms include options to extend the lease when it is reasonably certain the Company will exercise the option. For leases with a term of twelve months or less, the Company does not record a right-of-use asset and a lease liability and records lease expense on a straight-line basis. See Note 8 to the condensed consolidated financial statements.

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 within a single region 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. Depreciation, depletion and amortization in the table below include only amounts that are included in cost of revenues in the Company’s condensed consolidated statements of 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 expense and interest and other income (expense), net to its lime and limestone operations. Other revenues, gross profit and operating profit in the Company’s segment disclosures include the Company’s natural gas interests. Other identifiable assets include assets related to the Company’s natural gas interests, unallocated corporate assets and cash items.

The following table sets forth operating results and certain other financial data for the Company’s lime and limestone operations segment and other (in thousands):

The Company’s credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 2019 and November 21, 2019, 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 May 2, 2024.

Interest rates on the Revolving Facility are, at the Company’s option, LIBOR (or a replacement rate as determined by the Lender and the Company) 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 0.200% 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, 2022, the Company had no debt outstanding and no draws on the Revolving Facility other than $0.3 million of letters of credit, which count as draws against the available commitment under the Revolving Facility.

The Company has estimated that its effective income tax rate for 2022 will be 19.7%.

Accounting Policies (Policies)

Sep. 30, 2022

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 2022 and 2021 revenues was $12.3 million and $9.5 million, for the respective three-month periods ended September 30, and $34.0 million and $26.0 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.

Accounts Receivable

Accounts Receivable. 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. 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 is any meaningful asset-specific differences within its accounts receivable 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.

Leases

Leases. The Company determines if an arrangement is a lease at inception. When recording operating leases, the Company records a lease liability based on the net present value of the lease payments over the lease term, using the interest rate implicit in the lease, if known, or an incremental rate on a collateralized basis over a similar term and amount to the lease, and a corresponding right-of-use asset. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liabilities and operating lease liabilities, excluding current portion, on the condensed consolidated balance sheets. Lease expense is recognized over the lease term on a straight-line basis. Lease terms include options to extend the lease when it is reasonably certain the Company will exercise the option. For leases with a term of twelve months or less, the Company does not record a right-of-use asset and a lease liability and records lease expense on a straight-line basis. See Note 8 to the condensed consolidated financial statements.
