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, ~~2019.~~2020. The results of operations for the ~~three-and nine-month~~three- and six-month periods ended ~~September~~June 30, ~~2020~~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, subject to adjustment for working capital balances acquired.~~million cash. Carthage produces aggregate and pulverized limestone products that are used primarily in the agricultural, construction, roofing, and industrial industries. ~~Upon acquisition, Carthage’s assets and liabilities are included in the September 30, 2020 condensed consolidated balance sheet at fair value, with~~ ~~$7.5~~ ~~million of the purchase price preliminarily allocated to property, plant and equipment.~~ Carthage contributed $~~2.3~~2.5 and $4.7 million of revenues in the three- and ~~nine-month~~six-month periods ended ~~September~~June 30, ~~2020,~~2021, respectively, which are included in the condensed consolidated statements of operations. ~~The Company believes this acquisition will complement its existing geographic footprint.~~

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), ~~metals (including steel producers), oil and gas services,~~ roof shingle manufacturers, ~~and~~ 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.

During 2019, the Company’s natural gas interests did not reach any of the quantitative thresholds for a reportable segment, and the results from its natural gas interests are not expected to be of significance in future periods. The revenues, gross profit and operating profit of the natural gas interests are included in Other for reportable segment disclosures. Segment disclosures for the three- and nine-month periods ended September 30, 2019 have been recast to be consistent with the presentation for the respective periods ended September 30, 2020.

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 ~~2020~~2021 and ~~2019~~2020 revenues was $~~8.0~~

8.7 million and ~~$7.7~~$6.5 million, for the respective three-month periods ended ~~September~~June 30, and ~~$21.3~~$16.5 million and ~~$21.7~~$13.3 million for the respective ~~nine-month~~six-month periods ended ~~September~~June 30, which ~~approximate~~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.

Accounts Receivable. On January 1, 2020, the Company adopted ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 replaces the incurred impairment methodology in previous GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company applied the amendments of ASU 2016-13 using a modified-retrospective approach, and as a result, amounts recorded prior to January 1, 2020 have not been retrospectively restated. The implementation of ASU 2016-13 did not have a material impact on the Company’s results of operation, financial position, or cash flows.

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.~~

~~Comprehensive Income.~~ Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as mark-to-market gains or losses on foreign exchange derivative instruments designated as hedges, are reported as a separate component of the equity section of the balance sheet. Such items, along with net income, are components of comprehensive income. See Note 6 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.

~~Fair Values of Financial Instruments.~~ Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” The Company uses a three-tier fair value hierarchy, which classifies the inputs used in measuring fair values, in determining the fair value of its financial assets and liabilities. These tiers include: Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own

assumptions. Specific inputs used to value the Company’s foreign exchange hedges were Euro to U.S. Dollar exchange rates for the expected future payment dates for the Company’s commitments denominated in Euros. The last of these foreign exchange hedges expired in April 2020. See Note 6 to the condensed consolidated financial statements. There were no changes in the methods and assumptions used in measuring fair value during the period.

~~The Company’s financial liabilities measured at fair value on a recurring basis at September 30, 2020 and December 31, 2019, respectively, are summarized below (in thousands):~~

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.

During 2019, the Company’s natural gas interests did not reach any of the quantitative thresholds for a reportable segment, and the Company does not expect the results from its natural gas interests to be of significance in future periods. The Other revenues, gross profit and operating profit ~~from~~in the Company’s segment disclosures include the Company’s natural gas ~~interests are included in Other for the Company’s reportable segment disclosures.~~interests. Other identifiable assets include assets related to its natural gas interests, unallocated corporate assets and cash items. ~~Segment disclosures for the three and nine months ended September 30, 2019 have been recast to be consistent with the presentation for the three and nine months ended September 30, 2020.~~

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 ~~(“FX”)~~ hedges with ~~Wells Fargo Bank, N.A. (“Wells Fargo”) as the~~a counterparty to the FXforeign exchange hedges to fix the exchange rates. The last of the FXforeign exchange hedges expired in April 2020. The FXforeign exchange hedges were effective as defined under applicable accounting rules. Therefore, changes in the fair value of the FXforeign exchange hedges were reflected in comprehensive income.~~Due to changes in the U.S. Dollar, compared to the Euro, the fair value of the hedges resulted in net liabilities of $1 at December 31, 2019, which is included in accrued expenses.~~

7. Trade Receivables, Net

9. Banking Facilities and Debt

The Company’s credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 2019 and November 21, 2019, provides for a $75 million revolving credit facility (the “Revolving Facility”) and an incremental four year accordion feature to borrow up to an additional $50 million on the same terms, subject to approval by the Lender or another lender selected by the Company. The credit agreement also provides for a $10 million letter of credit sublimit under the Revolving Facility. The Revolving Facility and any incremental loans mature on May 2, 2024.

Interest rates on the Revolving Facility are, at the Company’s option, LIBOR (or a replacement rate as determined by the Lender and the Company) plus a margin of 1.000% to 2.000%, or the Lender’s Prime Rate plus a margin of 0.000% to 1.000%, and a commitment fee range of 0.200% to 0.350% on the undrawn portion of the Revolving Facility. The Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion, amortization and stock-based compensation expense (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period. Pursuant to a security agreement, dated August 25, 2004, the Revolving Facility is secured by the Company’s existing and hereafter acquired tangible assets, intangible assets and real property. The maturity of the Revolving Facility and any incremental loans can be accelerated if any event of default, as defined under the credit agreement, occurs. The Company’s maximum Cash Flow Leverage Ratio is 3.50 to 1.

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

As of ~~September~~June 30, ~~2020,~~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 ~~each of September 30, 2020 and~~ December 31, ~~2019~~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 ~~3.5%~~3.4% at ~~both September~~each of June 30, ~~2020~~2021 and December 31, ~~2019.~~ 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 ~~nine~~six months ended ~~September~~June 30, ~~2020~~2021 and ~~2019~~2020 were as follows (in thousands):

11. Income Taxes

The Company has estimated that its effective income tax rate for ~~2020~~2021 will be ~~18.2%~~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

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), ~~metals (including steel producers), oil and gas services,~~ roof shingle manufacturers, ~~and~~ 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, subject to adjustment for working capital balances acquired.~~cash. Carthage provides aggregate and pulverized limestone products that are used primarily in the ~~agricultural,~~agriculture, roofing, construction, ~~roofing,~~ and industrial industries. ~~Carthage’s assets and liabilities are included on our September 30, 2020 balance sheet at fair values, with $7.5 million preliminarily allocated to property, plant and equipment.~~ Carthage contributed ~~$2.3~~$2.5 million and $4.7 to our revenues for the ~~third quarter~~three- and ~~the nine months~~six-month periods ended ~~September~~June 30, ~~2020. We believe that this acquisition will complement our existing geographic footprint.~~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. ~~In the fourth quarter of 2019, we determined our natural gas interests did not reach any of the quantitative thresholds for a reportable segment.~~ 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. ~~Segment disclosures for the three- and nine-month periods ended September 30, 2019 have been recast to be consistent with the 2020 presentation for each respective period.~~

~~Revenues~~Our lime and limestone revenues increased ~~0.4%~~30.5% and ~~decreased 0.5%~~19.2% in the ~~third~~second quarter and first ~~nine~~six months ~~2020,~~2021, respectively, compared to the ~~third~~second quarter and first ~~nine~~six months ~~2019. Revenues from lime and limestone operations increased 0.5% and decreased 0.2% in the third quarter and first nine months 2020, respectively, compared to the comparable 2019 periods.~~

The increase in our lime and limestone revenues in the third quarter 2020, compared to the third quarter 2019, resulted primarily from an increase in sales to agriculture and roofing customers that was principally due to the addition of Carthage, partially offset by a 2.9% decrease in sales volumes for our lime and limestone products, primarily due to reduced demand from our oil and gas services, environmental, and construction customers. Third quarter 2020 revenues were also favorably impacted by a 3.4% increase in the average selling prices for our lime and limestone products.

The decrease in our lime and limestone revenues for the first nine months 2020, compared to the first nine months 2019, resulted primarily from a 4.5% decrease in sales volumes of our lime and limestone products, principally from the our oil and gas services, environmental, and steel customers, which was partially offset by increased demand from our construction customers, the additional sales provided by Carthage discussed above, and a 4.0% increase in the average selling prices for our lime and limestone products.

Gross profit increased 5.2% and 7.9% in the third quarter and first nine months 2020, respectively, compared to the third quarter and first nine months 2019. The increases in gross profit in the 2020 periods, compared to the comparable 2019 periods, resulted primarily from the increase in the average selling prices for our lime and limestone products, lower fuel costs, and increased operating efficiencies associated, in part, with the new kiln at our St. Clair facility, which began producing commercially saleable quicklime in the second quarter 2019, partially offset by increased costs incurred in the second and third quarters 2020 associated with responding to the COVID-19 pandemic.

The emergence of COVID-19 in the United States in the first quarter 2020 has created significant volatility, uncertainty and economic disruption to the general business environment. Federal, state, and local governmental responses to the COVID-19 pandemic, which include restrictions requiring social distancing and restrictions on business activities and movement of people in the markets for our lime and limestone products, began to take effect the last two weeks of March 2020. In the second quarter 2020, the COVID-19 pandemic and related governmental restrictions on business activities resulted in a general economic slowdown, which ~~has~~ disproportionately impacted certain industries that purchase our ~~lime and limestone~~ products, including oil and gas services, environmental, and steel. In addition to the ~~third quarter 2020, business activity began~~limestone sales by Carthage to ~~resume,~~agriculture, roofing and ~~pandemic-related restrictions were eased; however,~~construction customers, noted above, the ~~recent surge of COVID-19 cases~~increases in our lime and limestone revenues in the ~~United States could impact~~second quarter and first six months 2021 resulted primarily from increased sales to our construction, steel, roofing and environmental customers. In the ~~economic recovery that has occurred~~second quarter 2021, we also saw demand from our oil and gas services customers increase compared to ~~date.~~

~~We expect a continued slowdown~~the second quarter 2020. Revenues in ~~economic activity as restrictions continue, or even expand, which we anticipate will have an adverse impact on~~in the ~~demand~~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, particularly with respect to our customers in certain industries. In addition, a continued economic slowdown may put downward pressure on the prices we are able to realize for our~~ products. We will continue to be diligent on controlling our costs and finding ways to further increase operating efficiencies to mitigate some of the adverse effects of the decreases in demand resulting from the pandemic.

~~We continue to focus on the safety of our employees and individuals at our facilities that deliver~~Our lime and limestone ~~products~~gross profit increased 58.8% and 38.7% in the second quarter and first six months 2021, respectively, compared to the ~~essential businesses~~second quarter and ~~communities that we serve. In~~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 ~~addition~~recent months, which has continued to our standard health and safety protocols, we have implemented enhanced protocols at all of our locations, including at our newly acquired Carthage Crushed Limestone facility. These protocols include reduced access to facilities, screening of individuals on all sites, andreduce the ~~enforcement of social distancing and other practices that are consistent with, or exceed, the guidelines~~impact of the ~~Center for Disease Control and state and local authorities.~~

~~We are an essential~~pandemic on general business ~~and anticipate continuing to deliver lime and limestone products to all of the essential businesses we serve. Our lime and limestone products are used~~activities in the purification of drinking water, treatment of wastewater, and scrubbing of air emissions from incinerators, power plants, and industrial plants, as well as in the manufacture of paper and glass products. Our limestone is used in the production of animal feed and is also used in products that have been recognized as part of the Critical Infrastructure Sector, including steel and other metal products, and commercial, residential, and public works construction.

Future events or governmental responses to COVID-19 may impede or prevent our ability to operate at one or more of our manufacturing facilities or limit our ability to transport our products to our customers. For example, our lime and limestone products cannot be produced if all of our employees are required to work from home. Specialized and difficult to replace skill sets are also required in the production ofmarkets for our lime and limestone products. ~~Should one~~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 ~~more~~localized outbreaks of our facilities experience a COVID-19 outbreak requiring quarantining of employees possessing those skill sets, it would disrupt our ability to produce, sell, and deliver our lime and limestone products andthe 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

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 ~~$41.9~~$27.4 million in the first ~~nine~~six months ~~2020,~~2021, compared to ~~$36.2~~$27.1 million in the first ~~nine~~six months ~~2019,~~2020, an increase of ~~$5.7~~$0.2 million, or ~~15.8%~~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 ~~nine~~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 ~~$21.0~~$11.6 million net income, ~~$14.4~~$9.5 million DD&A, ~~$4.4~~$2.5 million deferred income taxes, ~~$1.3~~$0.8 million stock-based compensation, and a ~~$0.7~~$2.5 million increase from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first ~~nine~~six months 2020 included ~~an increase~~a decrease of ~~$0.8~~$1.8 million in trade receivables, net, due primarily from reduced revenues and favorable timing of collections in the second quarter, an increase of ~~$1.2~~$1.0 million in inventories, and an increase of ~~$2.3~~$0.8 million in accounts payable and accrued expenses, primarily ~~due to timing of payments on certain capital projects and the~~from deferral of the payment of certain payroll taxes provided for under the CARES Act in the second ~~and third quarters. In the first nine months 2019, net cash provided by operating activities was principally composed of $21.1~~quarter.

We had $17.8 million ~~net income, $12.6 million DD&A, $4.0 million deferred income taxes, $1.1 million stock-based compensation, and a $3.3 million decrease from changes~~ in ~~operating assets and liabilities. Changes in operating assets and liabilities~~capital expenditures in the first ~~nine~~six months ~~2019 included an increase of $3.6 million in trade receivables, net, and an increase of $0.7 million in accounts payable and accrued expenses.~~

~~Net cash used in investing activities was $22.0~~2021, compared to $10.6 million in the first ~~nine~~six months ~~2020 and included $13.6 million in capital~~2020. Capital expenditures ~~and $8.4 million for the acquisition of Carthage, compared to net cash used in investing activities of $20.2 million~~ in the first ~~nine~~six months ~~2019.~~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 ~~$2.9~~$1.8 million in the first ~~nine~~six months ~~2020,~~2021, compared to ~~$2.4~~$2.0 million in the first ~~nine~~six months ~~2019,~~2020, consisting primarily of cash dividends paid in each period.

Cash and cash equivalents increased ~~$17.1~~$7.8 million to ~~$71.3~~$91.3 million at ~~September~~June 30, ~~2020,~~2021, from ~~$54.3~~$83.6 million at December 31, ~~2019.~~2020.

We are not committed to any planned capital expenditures until actual orders are placed for equipment. As of ~~September~~June 30, ~~2020,~~2021, we did not have any material commitments for open purchase orders. ~~In October 2020, we entered into commitments totaling $5.0 million for the purchase of capital equipment.~~

Our credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 2019 and November 21, 2019, provides for a $75 million revolving credit facility (the “Revolving Facility”) and an incremental four-year accordion feature to borrow up to an additional $50 million on the same terms, subject to approval by the Lender or another lender selected by us. The credit agreement also provides for a $10 million letter of credit sublimit under the Revolving Facility. The Revolving Facility and any incremental loans mature on May 2, 2024.

Interest rates on the Revolving Facility are, at our option, LIBOR (or a replacement rate as determined by the Lender and the Company) plus a margin of 1.000% to 2.000%, or the Lender’s Prime Rate plus a margin of 0.000% to 1.000%; and a commitment fee range of 0.200% to 0.350% on the undrawn portion of the Revolving Facility. The Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based upon our Cash Flow Leverage Ratio, defined as the ratio of our total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion, amortization and stock-based compensation expense (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period. Pursuant to a security agreement, dated August 25, 2004, the Revolving Facility is secured by our existing and hereafter acquired tangible assets, intangible assets and real property. The maturity of the Revolving Facility and any incremental loans can be accelerated if any event of default, as defined under the credit agreement, occurs. Our maximum Cash Flow Leverage Ratio is 3.50 to 1.

We may pay dividends so long as we remain in compliance with the provisions of our credit agreement, and we may purchase, redeem or otherwise acquire shares of our common stock so long as our pro forma Cash Flow Leverage

Ratio is less than 3.00 to 1.00 and no default or event of default exists or would exist after giving effect to such stock repurchase.

At ~~September~~June 30, ~~2020,~~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. However, an extended period of severe economic disruption caused by the COVID-19 pandemic could negatively impact our cash flows from operations and our liquidity, although we have not experienced any material impacts on our cash flows from operations and liquidity to date.

Results of Operations.

Revenues in the ~~third~~second quarter ~~2020~~2021 were ~~$43.7~~$49.2 million, compared to ~~$43.6~~$37.5 million in the ~~third~~second quarter ~~2019,~~2020, an increase of ~~$0.2~~$11.6 million, or ~~0.4%~~30.9%.

Revenues from our lime and limestone operations in the ~~third~~second quarter ~~2020~~2021 increased ~~$0.2~~$11.4 million, or ~~0.5%~~30.5%, to ~~$43.5~~$48.7 million from ~~$43.3~~$37.4 million in the ~~third~~second quarter ~~2019.~~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 ~~increase~~increases in lime and limestone revenues in the ~~third~~second quarter ~~2020,~~and first six months 2021 were primarily due to increases in sales volumes of 28.3% and 17.4%, respectively, compared to the ~~third quarter 2019, resulted primarily from increased sales volumes of the Company’s lime and limestone products to our agriculture and roofing customers,~~comparable 2020 periods, principally due to increased demand from our construction, steel, roofing and environmental customers. In the ~~addition of Carthage, partially offset by a 2.9% decrease in sales volumes, primarily because of reduced~~second quarter 2021, we also saw demand from our oil and gas services ~~environmental, and construction customers. Third quarter 2020 revenues were also favorably impacted by a 3.4%~~customers increase ~~in the average prices for our lime and limestone products.~~

For the first nine months 2020, revenues from our lime and limestone operations decreased $0.3 million, or 0.2%, to $119.0 million compared to $119.3 million in the first nine months 2019. The decrease in revenues from our lime and limestone operations in the first nine months 2020 was primarily due to a 4.5% decrease in sales volumes compared to the first nine months 2019, principally due to reduced demand from our oil and gas services, environmental, and steel customers, partially offset by increased demand from our construction customers, the additional sales provided by Carthage discussed above, and a 4.0% average increase in prices for our lime and limestone products in the first nine months 2020, compared to the first nine months 2019.second quarter 2020. Revenues also included ~~$0.3~~$0.4 million and $0.7 million from our

natural gas interests in the ~~third~~second quarter and first ~~nine~~six months ~~2020,~~2021, respectively, compared to ~~$0.3~~$0.2 million and ~~$1.0~~$0.4 million in the comparable ~~2019~~2020 periods, respectively.

Gross profit was ~~$14.2~~$16.8 million and ~~$34.4~~$28.6 million in the ~~third~~second quarter and first ~~nine~~six months ~~2020,~~2021, respectively, compared to ~~$13.5~~$10.4 million and ~~$31.9~~$20.2 million in the comparable ~~2019~~2020 periods, increases of ~~$0.7~~$6.4 million and ~~$2.5~~$8.4 million, or ~~5.2%~~62.2% and ~~7.9%~~41.3%, respectively. Gross profit from our lime and limestone operations in the ~~third~~second quarter and first ~~nine~~six months ~~2020~~2021 was ~~$14.3~~$16.7 million and ~~$34.8~~$28.5 million, respectively, compared to ~~$13.5~~$10.5 million and ~~$31.9~~$20.5 million in the comparable ~~2019~~2020 periods, increases of ~~$0.8~~$6.2 million, or ~~5.8%~~58.8%, and ~~$2.9~~$8.0 million, or ~~9.3%~~38.7%, respectively. The increases in gross profit in the ~~2020~~2021 periods, compared to the comparable ~~2019~~2020 periods, resulted primarily from ~~lower fuel costs~~the increased revenues discussed above and increased operating efficiencies associated, in part, with the new kiln at our St. Clair facility, which began producing commercially saleable quicklime in the second quarter 2019, partially offset by increased costs incurred in the second and third quarters 2020 associated with responding to the COVID-19 pandemic.efficiencies. Gross profit also included ~~the impact of losses~~$113 thousand and $94 thousand from our natural gas interests in the second quarter and first six months 2021, respectively, compared to losses of ~~$74~~$150 thousand and ~~$386~~$312 thousand in the ~~third~~second quarter and first ~~nine~~six months 2020, ~~respectively, compared to profits of $6 thousand and $50 thousand in the comparable 2019 periods.~~respectively.

Selling, general and administrative ~~expenses~~ (“SG&A”) expenses were ~~$2.9 million and $9.0~~$3.0 million in the ~~third~~second quarter ~~and first nine months 2020, respectively,~~2021, compared to $2.9 million ~~and $8.2~~in the second quarter 2020, an increase of $0.1 million, or 2.6%. SG&A expenses were $6.0 million in the ~~comparable 2019 periods. As a percentage of revenues, SG&A was 6.7% and 7.5%~~first six months 2021, compared to $6.1 million in the ~~third quarter and~~ first ~~nine~~six months 2020, ~~respectively, compared to 6.8% in each~~a decrease of ~~the comparable 2019 periods. The increase in SG&A for the first nine months 2020 resulted primarily from increased~~$0.1 million, or 1.2%. Increased personnel expenses, including stock-based compensation, ~~increased~~during the 2021 periods were offset by the higher legal expenses ~~including acquisition-related legal fees, and COVID-19 pandemic costs~~ in the ~~second quarter 2020.~~2020 periods related to the acquisition of Carthage.

Interest expense was $62 thousand in each of the second quarters 2021 and ~~$186~~2020, and $124 thousand in each of the ~~third quarter~~first six months 2021 and ~~first nine months 2020, respectively, compared to $61 thousand and $183 thousand in the comparable 2019 periods.~~2020. We had no outstanding debt during any of the periods. Interest and other income, net was ~~$49 thousand~~$0.1 million in each of the second quarter and first six months 2021, compared to $0.1 million and $0.4 million, ~~in the third quarter and first nine months 2020,~~ respectively, ~~compared to $0.5 million and $1.5 million~~ in the comparable 2019 periods, decreases of $0.4 million and $1.1 million, or 89.7% and 72.6%, respectively. The decreases in interest income were due to reduced interest rates and lower average balances of cash and cash equivalents in the 2020 ~~periods, compared to the comparable 2019~~ periods.

Income tax expense was ~~$1.9~~$2.8 million and ~~$4.7~~$4.5 million in the ~~third~~second quarter and first ~~nine~~six months ~~2020,~~2021, respectively, compared to ~~$1.1~~$1.4 million and ~~$3.9~~$2.7 million, respectively, in the comparable ~~2019~~2020 periods. Our effective income tax rate ~~for each of the 2020 and 2019 periods~~ 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. Additionally, for the year ended December 31, 2019, our effective income tax rate was also reduced from the federal rate as a result of research and development tax credits. We do not expect a reduction in our income tax rate due to research and development tax credits in 2020.

Our net income was ~~$9.3~~$11.1 million ($~~1.65~~1.96 per share diluted) in the ~~third~~second quarter ~~2020,~~2021, compared to net income of ~~$9.9~~$6.1 million ($~~1.76~~1.08 per share diluted) in the second quarter 2020, an increase of $5.0 million, or 81.8%.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk.

We could be exposed to changes in interest rates, primarily as a result of floating interest rates on the Revolving Facility. There was no outstanding balance on the Revolving Facility subject to interest rate risk at ~~September~~June 30, ~~2020.~~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.

~~Foreign Exchange Risk.~~

Prior to April 2020, we had contracts related to the purchase and installation of equipment that required future payments in Euros and entered into foreign exchange hedges to fix our U.S. Dollar liability for these contracts. The last

~~of these foreign exchange hedges expired in April 2020. See Note 6 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 1A. RISK FACTORS~~

There have been no material changes from the risk factors set forth in Part I, Item 1A, “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, other than the additional risk factor provided below, which is an update to the risk factor included in Part II, Item 1A of our Quarterly Reports on Form 10-Q for the quarters ended March 31 and June 30, 2020. Please refer to that section of our Form 10-K for disclosures regarding what we believe are the material factors, risks, and uncertainties related to our financial condition, results of operations, cash flows, and competitive position.

~~Our financial condition, results of operations, cash flows, and competitive position could be materially adversely impacted by the COVID-19 pandemic~~. The extent to which COVID-19, and measures taken in response thereto, could materially adversely affect our financial condition, results of operations, cash flows, and competitive position will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities to contain the business, financial, and economic impact of the pandemic.

While we are continuing to execute our business continuity plans in response to the COVID-19 pandemic, there is the potential for increased disruptions to our lime and limestone business and operations from the pandemic. Federal, state, and local governmental responses to the COVID-19 pandemic, which include restrictions requiring social distancing and pandemic-related restrictions on business activities and movement of people in the markets for our lime and limestone products, began to take effect the last two weeks of March 2020. In the second quarter 2020, the pandemic and related restrictions on business activities have resulted in a general economic slowdown, which has disproportionately impacted certain industries that purchase our lime and limestone products, including oil and gas services, environmental, and steel. In the third quarter 2020, business activity began to resume, and restrictions were again eased; however, the recent surge of COVID-19 cases in the United States could impact the economic recovery that has occurred to date. We expect a continued slowdown in economic activity as restrictions continue, or even expand, which we anticipate will have an adverse impact on the demand for our lime and limestone products and increase our costs. In addition, a continued economic slowdown may put downward pressure on the prices we are able to realize for our products.

The continued impact of COVID-19 may limit our ability to produce, sell and deliver our lime and limestone products to our customers; cause key management and plant-level employees not to be available to us; result in plant shutdowns due to contagion, in which case we may not be able to shift production to our other plants; cause disruptions to our supply chain as it relates to our suppliers and other vendors, as well as disrupt the supply chains of our customers; impede our ability to maintain and repair our plants and equipment; negatively impact our modernization, expansion, and development plans; negatively impact our ability to integrate acquisitions; as well as adversely impact demand and prices for our lime and limestone products and increase our costs. Although we cannot predict future developments, which are highly uncertain, including the scope and duration of the pandemic and actions taken by governmental authorities to contain the impact of the pandemic, COVID-19 could have a material adverse effect on our financial condition, results of operations, cash flows, and competitive position.

ITEM 2: UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Our Amended and Restated 2001 Long-Term Incentive Plan allows employees and directors to pay the exercise price for stock options and the tax withholding liability upon the lapse of restrictions on restricted stock by payment in cash and/or delivery of shares of common stock. There were no repurchases in the ~~third~~second quarter ~~2020,~~2021 pursuant to these ~~provisions.~~provisions or otherwise.

ITEM 4: MINE SAFETY DISCLOSURES

Under Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of SEC Regulation S-K, each operator of a coal or other mine is required to include disclosures regarding certain mine safety results in its periodic reports filed with the SEC. The operation of our quarries, underground mine and plants is subject to regulation by the federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977. The required information regarding certain mining safety and health matters, broken down by mining complex, for the quarter ended ~~September~~June 30, ~~2020~~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.
