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, 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, 2022. The results of operations for the three-and six-month periods ended June 30, 2023 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 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.

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 2023 and 2022 revenues was $11.6 million and $12.1 million, for the respective three-month periods ended June 30, and $23.3 million and $21.7 million, for the respective six-month periods ended June 30, which approximates the amount of external freight included in cost of revenues. Sales taxes billed to customers are not included in revenues. For its natural gas interests, the Company recognizes revenue in the month of production and delivery.

Trade Receivables. 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 is 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 expense and interest and other income, net 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 six-month periods ended June 30, 2023 and 2022 for the Company’s lime and limestone operations segment and other are as follows (in thousands):

5. Income and Dividends Per Share of Common Stock

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


	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Net income for basic and diluted income per common share	$	19,712	$	10,238	$	36,816	$	18,906

Basic net income per common share	$	3.46	$	1.80	$	6.47	$	3.33
Diluted net income per common share	$	3.45	$	1.80	$	6.46	$	3.33

(1)	Excludes 17 and 14 stock options for the three- and six-month periods ended June 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 2023 periods as anti-dilutive.

The Company paid $0.20 and $0.40 of cash dividends per share of common stock in each of the three- and six- month periods ended June 30, 2023 and 2022, 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):


	June 30,		December 31,
	2023		2022
Lime and limestone inventories:
Raw materials	$	7,282	$	5,506
Finished goods		2,686		2,951
		9,968		8,457
Service parts inventories		12,382		11,122
	$	22,350	$	19,579

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 were scheduled to mature on May 2, 2024, prior to an amendment entered into on August 3, 2023, to extend the maturity date to August 3, 2028 and renew the four-year accordion feature.

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. Subsequent to the August 3, 2023 amendment, interest rates on the Revolving Facility are, at the

Company’s option, SOFR, plus a SOFR adjustment of 0.10%, plus a margin of 1.000% to 2.000%, or the Lender’s Prime Rate plus a margin of 0.000% to 1.000%, and a commitment fee range of 0.225% to 0.350% on the undrawn portion of the Revolving Facility. The Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion, amortization, and stock-based compensation expense (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period. Pursuant to a security agreement, dated August 25, 2004, the Revolving Facility is secured by the Company’s existing and hereafter acquired tangible assets, intangible assets, and real property. The maturity of the Revolving Facility and any incremental loans can be accelerated if any event of default, as defined under the credit agreement, occurs. The Company’s maximum Cash Flow Leverage Ratio is 3.50 to 1.

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

As of June 30, 2023, 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 0 to 6 years, with a weighted-average remaining lease term of 4 and 3 years at June 30, 2023 and December 31, 2022, respectively. Some operating leases include options to extend the leases for up to 5 years.

The components of lease costs for the three and six months ended June 30, 2023 and 2022 were as follows (in thousands):

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 June 16, 2023, the Company paid $1.1 million in cash dividends, based on a dividend rate of $0.20 per share of its common stock, to shareholders of record at the close of business on May 26, 2023. On March 17, 2023, 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 February 24, 2023.

11. Subsequent Event

On August 2, 2023, 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 September 15, 2023, to shareholders of record at the close of business on August 25, 2023.

On August 3, 2023, the Company amended its credit agreement with the Lender. The terms of the amended credit agreement provide for a final maturity date of the Revolving Facility and any incremental borrowings of August 3, 2028 and changes the benchmark rate to SOFR from LIBOR. Other key terms of the credit agreement, including the amounts provided for under the Revolving Facility and the four-year accordion feature, were unchanged by the amendment. See Note 7 to these condensed consolidated financial statements.

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 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 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.

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. Mill Creek contributed $1.1 million to our revenues for each of the three months ended June 30, 2023 and 2022, and $2.3 million and $1.9 million to our revenues for the six months ended June 30, 2023 and 2022, respectively.

In November 2022, we received objective evidence that a majority of the bargaining unit employees at our Arkansas facilities no longer supported union representation, and, accordingly, we withdrew recognition of the union. In June 2023, as part of a settlement with the National Labors Relations Board, we reinstated recognition of the union and have commenced negotiations of a new collective bargaining agreement with the union representing our Arkansas employees.

Our revenues increased 22.3% and 26.4% in the second quarter and first six months 2023, respectively, compared to the second quarter and first six months 2022. Revenues from our lime and limestone operations increased 23.6% in the second quarter 2023, compared to the second quarter 2022, due to a 21.3% increase in the average selling prices for our lime and limestone products, and a 2.3% increase in sales volumes of our lime and limestone products, principally due to increased demand from our environmental and oil and gas services customers, partially offset by decreased demand from our steel customers. Revenues from our lime and limestone operations increased 27.6% in the first six months 2023, compared to the first six months 2022, due to a 22.5% increase in the average selling prices for our lime and limestone products, and a 5.1% increase in sales volumes of our lime and limestone products, principally due to increased demand from our environmental customers, partially offset by decreased demand from our steel and industrial customers.

Our gross profit increased 64.6% and 65.2% in the second quarter and first six months 2023, respectively, compared to the second quarter and first six months 2022. Gross profit from our lime and limestone operations increased 69.8% and 69.6% in the second quarter and first six months 2023, respectively, compared to the second quarter and first six months 2022. The increases in gross profit in the periods were primarily from the increased revenues discussed above, partially offset by increased production costs, principally from higher energy, parts and supplies, and labor costs. Looking ahead for the remainder of 2023, we anticipate that economic uncertainty and higher interest rates could adversely impact future demand and prices for our products, particularly from our steel and construction customers.

Liquidity and Capital Resources.

Net cash provided by operating activities was $40.3 million in the first six months 2023, compared to $22.4 million in the first six months 2022, an increase of $17.9 million, or 80.2%. 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 six months 2023, net cash provided by operating activities was principally composed of $36.8 million net income, $11.8 million DD&A, and $1.6 million stock-based compensation, partially offset by $0.5 million deferred income taxes and a

$9.5 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first six months 2023 included an increase of $7.1 million in trade receivables, net, due primarily to increased sales in the second quarter 2023 compared to the fourth quarter 2022, and an increase of $2.8 million in inventories, net, partially offset by a decrease of $0.6 million in prepaid expenses and other current assets. In the first six months 2022, net cash provided by operating activities was principally composed of $18.9 million net income, $10.8 million DD&A, $1.2 million deferred income taxes, $1.3 million stock-based compensation, and a $9.8 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first six months 2022 included an increase of $10.0 million in trade receivables, net, due primarily from increased sales in the second quarter 2022 compared to the fourth quarter 2021, an increase of $1.4 million in inventories, net, and a $0.4 million increase in accounts payable and accrued expenses, partially offset by a decrease of $1.0 million in prepaid expenses and other current assets.

We had $15.4 million in capital expenditures in the first six months 2023, compared to $17.1 million in the first six months 2022, which included $5.6 million for the acquisition of Mill Creek. Net cash used in financing activities was $2.3 million in the first six months 2023, compared to $2.2 million in the first six months 2022, consisting primarily of cash dividends paid in each period.

Cash and cash equivalents increased $22.8 million to $156.2 million at June 30, 2023 from $133.4 million at December 31, 2022.

We are not committed to any planned capital expenditures until actual orders are placed for equipment. As of June 30, 2023, we did not have any material commitments for open purchase orders.

At June 30, 2023, our credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 2019 and November 21, 2019, provided 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 provided for a $10 million letter of credit sublimit under the Revolving Facility. On August 3, 2023, we entered into a tenth amendment, dated as of August 3, 2023 (the “Amendment”), to our credit agreement with our lender. We entered into the Amendment to extend the final maturity date of the Revolving Facility and any incremental borrowings to August 3, 2028, to renew the accordion feature, and to replace the LIBOR benchmark used in interest rate pricing with SOFR.

Interest rates on the Revolving Facility were, 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. Subsequent to the Amendment, interest rates on the Revolving Facility are, at our option, SOFR, plus a SOFR adjustment 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 June 30, 2023, 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 second quarter 2023 were $74.0 million, compared to $60.5 million in the second quarter 2022, an increase of $13.5 million, or 22.3%. For the first six months 2023, revenues were $140.8 million, compared to $111.4 million in the first six months 2022, an increase of $29.4 million, or 26.4%. Revenues from our lime and limestone operations were $73.7 million in the second quarter 2023, compared to $59.6 million in the second quarter 2022, an increase of $14.1 million, or 23.6%. For the first six months 2023, our lime and limestone revenues were $140.2 million, compared to $109.9 milling in the first six months 2022, an increase of $30.3 million, or 27.6%. The increase in our lime and limestone revenues in the second quarter 2023 resulted from increases in both 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 environmental and oil and gas services customers, partially offset by decreased demand from our steel customers. The increase in our lime and limestone revenues in the first six months 2023 resulted from increases in both 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 environmental customers, partially offset by decreased demand from our steel and industrial customers.

Gross profit was $27.1 million in the second quarter 2023, compared to $16.5 million in the second quarter 2022, an increase of $10.7 million, or 64.6%. Gross profit from our lime and limestone operations in the second quarter 2023 was $27.1 million, compared to $16.0 million in the second quarter 2022, an increase of $11.1 million, or 69.8%. The increase in lime and limestone gross profit in the second quarter 2023, compared to the second quarter 2022, resulted primarily from the increased revenues discussed above, partially offset by increased production costs, principally from higher energy, parts and supplies, and labor costs.

Gross profit was $51.1 million in the first six months 2023, compared to $30.9 million in the first six months 2022, an increase of $20.2 million, or 65.2%. Gross profit from our lime and limestone operations in the first six months 2023 was $51.2 million, compared to $30.2 million in the first six months 2022, an increase of $21.0 million or 69.6%. The increase in gross profit in the first six months 2023, compared to the first six months 2022, resulted primarily from the increased revenues discussed above, partially offset by our increased production costs.

Selling, general and administrative (“SG&A”) expenses were $4.3 million in the second quarter 2023, compared to $3.8 million in the second quarter 2022, an increase of $0.5 million, or 12.2%. SG&A expenses were $8.5 million in the first six months 2023, compared to $7.5 million in the first six months 2022, an increase of $1.0, or 13.2%. The increases in SG&A expenses in the 2023 periods, compared to the comparable 2022 periods, were primarily due to increased personnel expense.

Interest expense was $64 thousand and $128 thousand in the second quarter and first six months 2023, respectively, compared to $63 thousand and $126 thousand in the comparable 2022 periods. We had no outstanding debt during any of the periods. Interest and other income, net was $1.9 million and $3.5 million in the second quarter and first six months 2023, respectively, compared to $177 thousand and $237 thousand in the comparable 2022 periods. The increases in interest and other income, net during the 2023 periods, compared to the comparable 2022 periods, were due to higher interest rates on higher average balances in our cash and cash equivalents.

Income tax expense was $4.9 million and $9.2 million in the second quarter and first six months 2023, compared to $2.5 million and $4.7 million in the comparable 2022 periods. The increases in income tax expense in 2023 periods, compared to the comparable 2022 periods, were due to the increases in income before taxes.

Our net income was $19.7 million ($3.45 per share diluted) in the second quarter 2023, compared to net income of $10.2 million ($1.80 per share diluted) in the second quarter 2022, an increase of $9.5 million, or 92.5%. For the first six months 2023, our net income was $36.8 million ($6.46 per share diluted), compared to $18.9 million ($3.33 per share diluted) in the first six months 2022, an increase of $17.9 million, or 94.7%.

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 June 30, 2023. 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 second quarter 2023 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 June 30, 2023 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.
