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, 2020. The results of operations for the three- and six-month periods ended June 30, 2021 are not necessarily indicative of operating results for the full year.

On July 1, 2020, the Company acquired 100% of the equity interest of Carthage Crushed Limestone (“Carthage”), a limestone mining and production company located in Carthage, Missouri, for $8.4 million cash. Carthage produces aggregate and pulverized limestone products that are used primarily in the agricultural, construction, roofing, and industrial industries. Carthage contributed $2.5 and $4.7 million of revenues in the three- and six-month periods ended June 30, 2021, respectively, which are included in the condensed consolidated statements of operations.

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, Colorado Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company – Shreveport, U.S. Lime Company – St. Clair, ART Quarry TRS LLC (DBA Carthage Crushed Limestone) and U.S. Lime Company – Transportation. In addition, the Company, through its wholly owned subsidiary, U.S. Lime Company – O & G, LLC, has royalty and non-operated working interests in natural gas wells located in Johnson County, Texas, in the Barnett Shale Formation.

3. Accounting Policies

Revenue Recognition. The Company recognizes revenue for its lime and limestone operations when (i) a contract with the customer exists and the performance obligations are identified; (ii) the price has been established; and (iii) the performance obligations have been satisfied, which is generally upon shipment. The Company’s returns and allowances are minimal. Revenues include external freight billed to customers with related costs accounted for as fulfillment costs and included in cost of revenues. External freight billed to customers included in 2021 and 2020 revenues was $8.7 million and $6.5 million, for the respective three-month periods ended June 30, and $16.5 million and $13.3 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.

The Company operates its lime and limestone operations within a single geographic region and derives all revenues from that segment from the sale of lime and limestone products. See Note 4 to the condensed consolidated financial statements for disaggregation of revenues by segment, which the Company believes best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

7

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. See Note 7 to the condensed consolidated financial statements.

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 10 to the condensed consolidated financial statements.

4. Business Segment

The Company has identified 1 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 its 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 its natural gas interests, unallocated corporate assets and cash items.

5. Income Per Share of Common Stock

On April 30, 2021, the shareholders approved an increase in the Company’s number of authorized shares of common stock from 15,000,000 to 30,000,000. At June 30, 2021, the Company had 30,000,000 shares of common stock authorized and 5,658,481 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 June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Net income for basic and diluted income per common share	$	11,093	$	6,101	$	18,124	$	11,645
Weighted-average shares for basic income per common share		5,657		5,629		5,654		5,627
Effect of dilutive securities:
Employee and director stock options(1)		12		8		13		9
Adjusted weighted-average shares and assumed exercises for diluted income per common share		5,669		5,637		5,667		5,636
Basic net income per common share	$	1.96	$	1.08	$	3.21	$	2.07
Diluted net income per common share	$	1.96	$	1.08	$	3.20	$	2.07

(1) Excludes 15 and 11 stock options for the three- and six-month 2020 periods, respectively, as anti-dilutive because the exercise price exceeded the average per share market price for the period.

6. Accumulated Other Comprehensive Income

The following table presents the components of comprehensive income (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Net income	$	11,093	$	6,101	$	18,124	$	11,645

Deferred income tax expense		—		(2)		—		—
Comprehensive income	$	11,093	$	6,108	$	18,124	$	11,646

In May 2018, to hedge against potential losses due to changes in the Euro to U.S. Dollar exchange rates, the Company entered into foreign exchange hedges with a counterparty to the foreign exchange hedges to fix the exchange rates. The last of the foreign exchange hedges expired in April 2020. The foreign exchange hedges were effective as defined under applicable accounting rules. Therefore, changes in the fair value of the foreign exchange hedges were reflected in comprehensive income.

(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.

11

As of June 30, 2021, the Company had 0 debt outstanding and no draws on the Revolving Facility other than $0.4 million of letters of credit, which count as draws against the available commitment under the Revolving Facility.

10. 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 7 years, with a weighted-average remaining lease term of 2 years at June 30, 2021 and 3 years at December 31, 2020. Some operating leases include options to extend the leases for up to 5 years. The liability for the Company’s operating leases was discounted to present value using a weighted-average discount rate of 3.4% at each of June 30, 2021 and December 31, 2020. On July 12, 2021, the Company amended and extended the lease of its Dallas, Texas corporate office through November 2028.

The components of lease costs for the three and six months ended June 30, 2021 and 2020 were as follows (in thousands):

11. Income Taxes

The Company has estimated that its effective income tax rate for 2021 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.

12. Dividends

On June 11, 2021, the Company paid $0.9 million in cash dividends, based on a dividend of $0.16 per share of its common stock, to shareholders of record at the close of business on May 21, 2021. On March 12, 2021, the Company paid $0.9 million in cash dividends, based on a dividend of $0.16 per share of its common stock, to shareholders of record at the close of business on February 19, 2021.

13. Subsequent Event

On July 28, 2021, the Company’s Board of Directors declared a regular quarterly cash dividend of $0.16 per share on the Company’s common stock. This dividend is payable on September 10, 2021 to shareholders of record at the close of business on August 20, 2021.

Overview.

We have identified one reportable business segment based on the distinctness of our activities and products: lime and limestone operations. All of our operations are in the United States. Operating profit from our lime and limestone operations includes all of our selling, general and administrative costs. We do not allocate interest expense and interest and other income (expense), net to our lime and limestone operations.

Through our lime and limestone operations, 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, Colorado Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company – Shreveport, U.S. Lime Company – St. Clair, ART Quarry TRS LLC (DBA Carthage Crushed Limestone) and U.S. Lime Company – Transportation. The lime and limestone operations represent our principal business.

On July 1, 2020, we acquired Carthage Crushed Limestone (“Carthage”), a limestone mining and production company located in Carthage, Missouri, for $8.4 million cash. Carthage provides aggregate and pulverized limestone products that are used primarily in the agriculture, roofing, construction, and industrial industries. Carthage contributed $2.5 million and $4.7 to our revenues for the three- and six-month periods ended June 30, 2021, respectively.

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.

Our lime and limestone revenues increased 30.5% and 19.2% in the second quarter and first six months 2021, respectively, compared to the second quarter and first six months 2020. In the second quarter 2020, the COVID-19 pandemic and related governmental restrictions on business activities resulted in a general economic slowdown, which disproportionately impacted certain industries that purchase our products, including oil and gas services, environmental, and steel. In addition to the limestone sales by Carthage to agriculture, roofing and construction customers, noted above, the increases in our lime and limestone revenues in the second quarter and first six months 2021 resulted primarily from increased sales to our construction, steel, roofing and environmental customers. In the second quarter 2021, we also saw demand from our oil and gas services customers increase compared to the second quarter 2020. Revenues in in the second quarter and first six months 2021 were also favorably impacted by increases in the average selling prices of 2.2% and 1.8%, respectively, for our lime and limestone products.

Our lime and limestone gross profit increased 58.8% and 38.7% in the second quarter and first six months 2021, respectively, compared to the second quarter and first six months 2020. The increases in gross profit in the 2021 periods, compared to the comparable 2020 periods, resulted primarily from the increased revenues discussed above and increased operating efficiencies.

Federal, state, and local governmental restrictions in response to the COVID-19 pandemic have generally been lifted or curtailed in recent months, which has continued to reduce the impact of the pandemic on general business activities in the markets for our lime and limestone products. In the locations where we operate, normal business activities have largely resumed. With the resumption of normal business activities, we are experiencing lower availability of labor and certain supplies and services and rising costs. Additionally, new variants of COVID-19 and the possibility of new wide-spread or localized outbreaks of the virus could have a material adverse effect on our financial condition, results of operations, cash flows and competitive position.

Looking ahead, we anticipate continued challenges in the availability and costs of labor and supplies and services for a period of time, while the broader economy adjusts to its reopened status, and we will continue to monitor the evolving COVID-19 situation and adjust our operations accordingly.

At our 2021 Annual Meeting of Shareholders, our shareholders approved an increase in the number of our authorized shares of common stock from 15,000,000 to 30,000,000. Possible uses of the additional authorized shares

15

include, without limitation, future stock splits, stock dividends, rights offerings, acquiring other companies, businesses or products in exchange for shares, attracting and retaining employees by the issuance of additional shares under our Amended and Restated 2001 Long-Term Incentive Plan and any future equity compensation plans, issuance of securities convertible into shares, and other transactions and corporate purposes which our Board of Directors deems to be in the best interests of us and our shareholders.

Liquidity and Capital Resources.

Net cash provided by operating activities was $27.4 million in the first six months 2021, compared to $27.1 million in the first six months 2020, an increase of $0.2 million, or 0.9%. 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 2021, net cash provided by operating activities was principally composed of $18.1 million net income, $10.6 million DD&A, $1.8 million deferred income taxes, $1.1 million stock-based compensation, and a $4.1 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first six months 2021 included an increase of $4.5 million in trade receivables, net, due primarily from increased sales in the second quarter 2021 compared to the fourth quarter 2020, a decrease of $0.6 million in inventories, and a decrease of $0.6 million in accounts payable and accrued expenses. In the first six months 2020, net cash provided by operating activities was principally composed of $11.6 million net income, $9.5 million DD&A, $2.5 million deferred income taxes, $0.8 million stock-based compensation, and a $2.5 million increase from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first six months 2020 included a decrease of $1.8 million in trade receivables, net, due primarily from reduced revenues and favorable timing of collections in the second quarter, an increase of $1.0 million in inventories, and an increase of $0.8 million in accounts payable and accrued expenses, primarily from deferral of the payment of certain payroll taxes provided for under the CARES Act in the second quarter.

We had $17.8 million in capital expenditures in the first six months 2021, compared to $10.6 million in the first six months 2020. Capital expenditures in the first six months 2021 included $7.0 million of investment to develop our Love Hollow Quarry and improve the transportation infrastructure between the Love Hollow Quarry and our Arkansas Lime production facilities. Net cash used in financing activities was $1.8 million in the first six months 2021, compared to $2.0 million in the first six months 2020, consisting primarily of cash dividends paid in each period.

Cash and cash equivalents increased $7.8 million to $91.3 million at June 30, 2021, from $83.6 million at December 31, 2020.

We are not committed to any planned capital expenditures until actual orders are placed for equipment. As of June 30, 2021, 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

16

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, 2021, we had no debt outstanding and no draws on the Revolving Facility other than $0.4 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 2021 were $49.2 million, compared to $37.5 million in the second quarter 2020, an increase of $11.6 million, or 30.9%. For the first six months 2021, revenues were $90.8 million, compared to $76.0 million in the first six months 2020, an increase of $14.8 million, or 19.5%. Revenues from our lime and limestone operations in the second quarter 2021 increased $11.4 million, or 30.5%, to $48.7 million from $37.4 million in the second quarter 2020. For the first six months 2021, revenues from our lime and limestone operations increased $14.5 million, or 19.2%, to $90.1 million, compared to $75.6 million in the first six months 2020. The increases in lime and limestone revenues in the second quarter and first six months 2021 were primarily due to increases in sales volumes of 28.3% and 17.4%, respectively, compared to the comparable 2020 periods, principally due to increased demand from our construction, steel, roofing and environmental customers. In the second quarter 2021, we also saw demand from our oil and gas services customers increase compared to the second quarter 2020. Revenues also included $0.4 million and $0.7 million from our natural gas interests in the second quarter and first six months 2021, respectively, compared to $0.2 million and $0.4 million in the comparable 2020 periods, respectively.

Gross profit was $16.8 million and $28.6 million in the second quarter and first six months 2021, respectively, compared to $10.4 million and $20.2 million in the comparable 2020 periods, increases of $6.4 million and $8.4 million, or 62.2% and 41.3%, respectively. Gross profit from our lime and limestone operations in the second quarter and first six months 2021 was $16.7 million and $28.5 million, respectively, compared to $10.5 million and $20.5 million in the comparable 2020 periods, increases of $6.2 million, or 58.8%, and $8.0 million, or 38.7%, respectively. The increases in gross profit in the 2021 periods, compared to the comparable 2020 periods, resulted primarily from the increased revenues discussed above and increased operating efficiencies. Gross profit also included $113 thousand and $94 thousand from our natural gas interests in the second quarter and first six months 2021, respectively, compared to losses of $150 thousand and $312 thousand in the second quarter and first six months 2020, respectively.

Selling, general and administrative (“SG&A”) expenses were $3.0 million in the second quarter 2021, compared to $2.9 million in the second quarter 2020, an increase of $0.1 million, or 2.6%. SG&A expenses were $6.0 million in the first six months 2021, compared to $6.1 million in the first six months 2020, a decrease of $0.1 million, or 1.2%. Increased personnel expenses, including stock-based compensation, during the 2021 periods were offset by the higher legal expenses in the 2020 periods related to the acquisition of Carthage.

Interest expense was $62 thousand in each of the second quarters 2021 and 2020, and $124 thousand in each of the first six months 2021 and 2020. We had no outstanding debt during any of the periods. Interest and other income, net was $0.1 million in each of the second quarter and first six months 2021, compared to $0.1 million and $0.4 million, respectively, in the comparable 2020 periods.

Income tax expense was $2.8 million and $4.5 million in the second quarter and first six months 2021, respectively, compared to $1.4 million and $2.7 million, respectively, in the comparable 2020 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 $11.1 million ($1.96 per share diluted) in the second quarter 2021, compared to net income of $6.1 million ($1.08 per share diluted) in the second quarter 2020, an increase of $5.0 million, or 81.8%. Net income in the first six months 2021 was $18.1 million ($3.20 per share diluted), an increase of $6.5 million, or 55.6%, compared to net income of $11.6 million ($2.07 per share diluted) in the first six months 2020.

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, 2021. Any future borrowings under the Revolving Facility would be subject to interest rate risk. See Note 9 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 2021 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, 2021 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.
