UNITED STATES LIME & MINERALS, INC. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

(Unaudited)

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-month period ended March 31, 2023 are not necessarily indicative of operating results for the full year.

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. Mill Creek contributed $1.2 million and $0.8 million to the Company’s revenues for the three months ended March 31, 2023 and 2022, respectively.

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 $9.6 million, for the respective three-month periods ended March 31, 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 6

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.

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 months ended March 31, 2023 and 2022 for the Company’s lime and limestone operations segment and other are as follows (in thousands):

The Company paid $0.20 of cash dividends per share of common stock in each of the three months ended March 31, 2023 and 2022.

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):


	March 31,		December 31,
	2023		2022

Service parts inventories		11,692		11,122
	$	22,046	$	19,579

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, 8

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 March 31, 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.

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 March 31, 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 months ended March 31, 2023 and 2022 were as follows (in thousands):


				Three Months Ended March 31,
		Classification	****	2023		****	2022		****
Operating lease costs^(1)^		Cost of revenues		$	770		$	522
Operating lease costs^(1)^		Selling, general and administrative expenses			41			66
Rental revenues		Interest and other income, net			(16)			(32)
Net operating lease costs				$	795		$	556
(1)	Includes the costs of leases with a term of one year or less.
---	---

As of March 31, 2023, future minimum payments under operating leases that were either non-cancelable or subject to significant penalty upon cancellation, including future minimum payments under renewal options that the Company is reasonably certain to exercise, were as follows (in thousands):



2023 (excluding the three months ended March 31, 2023)	$	1,105
2024		1,445
2025		1,187
2026		1,106
2027		694
Thereafter		250
Total future minimum lease payments		5,787
Less imputed interest		(285)
Present value of lease liabilities	$	5,502

Supplemental cash flow information pertaining to the Company’s leasing activity for the three months ended March 31, 2023 and 2022 is as follows (in thousands):


	Three Months Ended March 31,
	2023		2022
Cash payments for lease liabilities included in operating cash flows	$	417	$	349
Right-of-use assets obtained in exchange for operating lease obligations	$	81	$	492

Income Taxes

The Company has estimated that its effective income tax rate for 2023 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.

Dividends

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.

Subsequent Event

On May 3, 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 June 16, 2023, to shareholders of record at the close of business on May 26, 2023. 10

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 $1.2 million and $0.8 million to our revenues for the three months ended March 31, 2023 and 2022, respectively.

Our revenues increased 31.2% in the first quarter 2023, compared to the first quarter 2022. Revenues from our Lime and Limestone Operations increased 32.3% in the first quarter 2023, compared to the first quarter 2022, primarily due to a 23.5% increase in the average selling prices for our lime and limestone products, and an 8.8% increase in sales volumes of our lime and limestone products, principally due to increased demand from our construction customers.

Our gross profit increased 65.8% in the first quarter 2023, compared to the first quarter 2022. Gross profit from our Lime and Limestone Operations increased 69.5% in the first quarter 2023, compared to the first quarter 2022, primarily from the increased revenues discussed above, partially offset by increased production costs, principally from higher energy, transportation, and labor costs. Looking ahead for the remainder of 2023, we anticipate continuing pressure on our lime and limestone production costs and believe general recessionary concerns could potentially impact future demand for our products.

Liquidity and Capital Resources.

Net cash provided by operating activities was $20.6 million in the first quarter 2023, compared to $8.1 million in the first quarter 2022, an increase of $12.6 million, or 156.2%. 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 quarter 2023, net cash provided by operating activities was principally composed of $17.1 million net income, $5.8 million DD&A, and $0.8 million stock-based compensation, partially offset by $0.2 million deferred income taxes and a $2.9 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first quarter 2023 included an increase of $4.8 million in trade receivables, net, due primarily to increased sales in the first quarter 2023 compared to the fourth quarter 2022, and an increase of $2.5 million in inventories, partially offset by a $3.7 million increase in accounts payable and accrued expenses and a decrease of $0.6 million in prepaid expenses and other current assets. In the first quarter 2022, net cash provided by operating activities was principally composed of $8.7 million net income, $5.3 million DD&A, $0.4 million deferred income taxes, $0.7 million stock-based compensation, and a $6.9 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first quarter 2022 included an increase of $5.7 million in trade receivables, net, due primarily from increased sales in the first quarter 2022 compared to the fourth quarter 2021, an increase of $1.3 million in inventories, and a $1.0 million decrease in accounts payable and accrued expenses, partially offset by a decrease of $1.0 million in prepaid and other assets.

We had $5.5 million in capital expenditures in the first quarter 2023, compared to $11.4 million in the first quarter 2022, which included $5.9 million for the acquisition of Mill Creek. Net cash used in financing activities was 12

$1.1 million in the first quarter 2023, compared to $1.2 million in the first quarter 2022, consisting primarily of cash dividends paid in each period.

Cash and cash equivalents increased $14.2 million to $147.6 million at March 31, 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 March 31, 2023, 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 March 31, 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 first quarter 2023 were $66.8 million, compared to $50.9 million in the first quarter 2022, an increase of $15.9 million, or 31.2%. Revenues from our Lime and Limestone Operations were $66.5 million in the first quarter 2023, compared to $50.3 million in the first quarter 2022, an increase of $16.2 million, or 32.3%. The increase in our revenues in the first quarter 2023, compared to the first quarter 2022, 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 construction customers.

Gross profit was $24.0 million in the first quarter 2023, compared to $14.5 million in the first quarter 2022, an increase of $9.5 million, or 65.8%. Gross profit from our Lime and Limestone Operations in the first quarter 2023 was $24.1 million, compared to $14.2 million in the first quarter 2022, an increase of $9.9 million, or 69.5%. The increase in lime and limestone gross profit in the first quarter 2023, compared to the first quarter 2022, resulted primarily from the increased revenues discussed above, partially offset by increased production costs, principally from higher energy, transportation, and labor costs.

Selling, general and administrative (“SG&A”) expenses were $4.2 million in the first quarter 2023, compared to $3.6 million in the first quarter 2022, an increase of $0.5 million, or 14.2%. The increase in SG&A expenses was primarily due to increased personnel expense. 13

Interest expense was $64 thousand and $63 thousand in the first quarter 2023 and 2022, respectively. We had no outstanding debt during any of the periods. Interest and other income, net was $1.6 million and $60 thousand in the first quarter 2023 and 2022, respectively. The $1.5 million increase in interest and other income, net during the first quarter 2023, compared to the first quarter 2022, was due to higher interest rates on higher average balances in our cash and cash equivalents.

Income tax expense was $4.2 million in the first quarter 2023, compared to $2.2 million in the first quarter 2022. The increase in income tax expense in the first quarter 2023, compared to the first quarter 2022, was due to the increase in income before taxes.

Our net income was $17.1 million ($3.00 per share diluted) in the first quarter 2023, compared to net income of $8.7 million ($1.53 per share diluted) in the first quarter 2022, an increase of $8.4 million, or 97.3%.

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 March 31, 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. In the first quarter 2023, pursuant to these provisions, we purchased 646 shares at a price of $151.70, the fair market value of one share of our common stock on the date they were tendered for payment of tax withholding liability upon the lapse of restrictions on restricted stock.

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 March 31, 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 14

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

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

EXHIBIT 95.1

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 March 31, 2023, and all pending legal actions as of March 31, 2023. 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 March 31, 2023 were taken from the MSHA system as of May 2, 2023.

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.

---	---
(3)	Includes any pending legal actions before the Commission involving such mine as of March 31, 2023. 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 1 legal action instituted during the reporting period.
---	---

Pattern or Potential Pattern of Violations*.* During the quarter ended March 31, 2023, 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
