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

2. Organization

The Company is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and building contractors), industrial (including paper and glass manufacturers), 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) 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 six-month periods ended June 30, 2019 have been recast to be consistent with the presentation for the respective periods ended June 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. Revenues include external freight billed to customers with related costs accounted for as fulfillment costs and included in cost of revenues. The Company’s returns and allowances are minimal. External freight billed to customers included in 2020 and 2019 revenues was $6.5 million and $7.1 million, for the respective three-month periods ended June 30, and $13.3 million and $13.9 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. 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.

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 balance sheet. 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 June 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 revenues, gross profit and operating profit from the Company’s natural gas interests are included in Other for the Company’s reportable segment disclosures. Other identifiable assets include assets related to its natural gas interests, unallocated corporate assets and cash items. Segment disclosures for the three and six months ended June 30, 2019 have been recast to be consistent with the presentation for the three and six months ended June 30, 2020.

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

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,
	2020		2019		2020		2019
Net income	$	6,101	$	6,033	$	11,645	$	11,161

Deferred income tax expense		(2)		(7)		—		(1)
Comprehensive income	$	6,108	$	6,058	$	11,646	$	11,166

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 counterparty to the FX hedges to fix the exchange rates. The last of the FX hedges expired in April 2020. The FX hedges were effective as defined under applicable accounting rules. Therefore, changes in the fair value of the FX 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

Additions (reductions) and write-offs to the Company’s allowance for credit losses for the six months ended June 30, 2020 and 2019 were as follows (in thousands):

	$	14,422	$	13,388

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 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 June 30, 2020, 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 3 years at both June 30, 2020 and December 31, 2019. 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% at both June 30, 2020 and December 31, 2019. The components of lease costs for the three and six months ended June 30, 2020 and 2019 were as follows (in thousands):

11

		Three Months Ended June 30,				Six Months Ended June 30,
	Classification	2020		2019		2020		2019

⁽¹⁾ Includes the costs of leases with a term of 12 months or less.

As of June 30, 2020, 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):

2020 (excluding the six months ended June 30, 2020)	$	658
2021		1,077
2022		443
2023		189

Supplemental cash flow information pertaining to the Company’s leasing activity for the six months ended June 30, 2020 and 2019 were as follows (in thousands):

	Six Months Ended June 30,
	2020		2019
Cash payments for operating lease liabilities	$	821	$	950
Right-of-use assets obtained in exchange for operating lease obligations	$	53	$	857

11. Income Taxes

The Company has estimated that its effective income tax rate for 2020 will be 18.9%. 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.

12. Dividends

On June 12, 2020, 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 22, 2020. On March 13, 2020, 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 21, 2020.

13. Subsequent Events

On July 1, 2020, the Company acquired Carthage Crushed Limestone, a limestone mining and production company located in Carthage, Missouri for $9 million cash, subject to adjustment.

On July 29, 2020, 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 18, 2020 to shareholders of record at the close of business on August 28, 2020.

Overview.

We have identified one reportable business segment based on the distinctness of our activities and products: lime and limestone operations. All 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

14

manufacturers), 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) industries. We are headquartered in Dallas, Texas and operate lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, 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.

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 six-month periods ended June 30, 2019 have been recast to be consistent with the 2020 presentation for each respective period.

On July 1, 2020, we acquired 100% of the equity interest of Carthage Crushed Limestone, a limestone mining and production company located in Carthage, Missouri, for $9 million cash, subject to adjustment. We believe that this acquisition will complement our existing geographic footprint.

Revenues decreased 3.6% and 1.0% in the second quarter and first six months 2020, respectively, compared to the second quarter and first six months 2019. Revenues from lime and limestone operations decreased 3.2% and 0.6% in the second quarter and first six months 2020, respectively, compared to the comparable 2019 periods. The decreases in lime and limestone revenues in the second quarter and first six months 2020 resulted primarily from decreased sales volumes of 7.5% and 4.8%, respectively, principally due to reduced demand from our oil and gas services, steel and environmental customers, partially offset by increased demand from our construction customers. The decreased sales volumes were also partially offset by increases in average prices realized for our lime and limestone products of 4.3% and 4.2% in the second quarter and first six months 2020, respectively, compared to the comparable 2019 periods.

Gross profit increased 6.5% and 9.8% in the second quarter and first six months 2020, respectively, compared to the second quarter and first six months 2019. The increases in gross profit in the 2020 periods, compared to the comparable 2019 periods, resulted primarily from 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 the decreased revenues described above and increased costs incurred in the second quarter 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. While many of these restrictions began to be lifted in the second quarter 2020, the easing of restrictions has subsequently been halted or reversed in much of our geographic footprint.

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 environmental, oil and gas drilling, and steel. 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. 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 focus on cost-cutting initiatives and ways to further increase operating efficiencies in an effort to mitigate some of the effects of the ongoing economic downturn, including decreased demand for our products and increases in costs.

As we continue to respond to these unprecedented times caused by the COVID-19 pandemic, we have not wavered in our commitment to the safety of our employees and individuals at our facilities that deliver lime and limestone products to the essential businesses and communities that we serve. In addition 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

15

all sites, and the enforcement of social distancing and other practices that are consistent with, or exceed, the guidelines of the Center for Disease Control and state and local authorities.

We are an essential 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 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 of our lime and limestone products. Should one or more 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 and could have a material adverse effect on our financial condition, results of operations, cash flows, and competitive position.

Liquidity and Capital Resources.

Net cash provided by operating activities was $27.1 million in the first six months 2020, compared to $20.0 million in the first six months 2019, an increase of $7.1 million, or 35.4%. Our net cash provided by operating activities is composed of net income, depreciation, depletion and amortization (“DD&A”), deferred income taxes, other non-cash items included in net income and changes in working capital. 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, 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, and a decrease of $0.9 million in prepaid expenses and other assets. In the first six months 2019, net cash provided by operating activities was principally composed of $11.2 million net income, $8.4 million DD&A, $2.6 million deferred income taxes, $0.7 million stock-based compensation, and a $2.9 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first six months 2019 included an increase of $3.3 million in trade receivables, net, and a decrease of $0.5 million in inventories, net.

We had $10.6 million in capital expenditures in the first six months 2020, compared to $12.4 million in the first six months 2019. Net cash used in financing activities was $2.0 million in the first six months 2020, compared to $1.7 million in the first six months 2019, consisting primarily of cash dividends paid in each period.

Cash and cash equivalents increased $14.6 million to $68.8 million at June 30, 2020, from $54.3 million at December 31, 2019.

We are not committed to any planned capital expenditures until actual orders are placed for equipment. As of June 30, 2020, we did not have any material commitments for open purchase orders. As previously discussed, on July 1, 2020, we acquired 100% of the equity interest of Carthage Crushed Limestone for $9 million cash, subject to adjustment.

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 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-

16

based compensation expense (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period. Pursuant to a security agreement, dated August 25, 2004, the Revolving Facility is secured by our existing and hereafter acquired tangible assets, intangible assets and real property. The maturity of the Revolving Facility and any incremental loans can be accelerated if any event of default, as defined under the credit agreement, occurs. Our maximum Cash Flow Leverage Ratio is 3.50 to 1.

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

At June 30, 2020, 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 second quarter 2020 were $37.5 million, compared to $39.0 million in the second quarter 2019, a decline of $1.4 million, or 3.6%. For the first six months 2020, revenues were $76.0 million, compared to $76.8 million in the first six months 2019, a decrease of $0.8 million, or 1.0%. Revenues from our lime and limestone operations in the second quarter 2020 decreased $1.2 million, or 3.2%, to $37.4 million from $38.6 million in the second quarter 2019. For the first six months 2020, revenues from our lime and limestone operations decreased $0.5 million, or 0.6%, to $75.6 million compared to $76.0 million in the first six months 2019. As discussed above, the decrease in revenues from our lime and limestone operations in the second quarter and first six months 2020 was primarily due to decreased sales volumes of 7.5% and 4.8%, respectively, compared to the comparable 2019 periods, principally due to reduced demand from our environmental, oil and gas services and steel customers, partially offset by increased demand from our construction customers, which had been negatively impacted by increased rainfall in Texas in the second quarter 2019. Additionally, the reductions in sales volumes were partially offset by average increases in prices for our lime and limestone products in the second quarter and first six months 2020 of 4.3% and 4.2%, respectively, compared to the comparable 2019 periods. Revenues also included $0.2 million and $0.4 million from our natural gas interests in the second quarter and first six months 2020, respectively, compared to $0.4 million and $0.7 million in the comparable 2019 periods, respectively.

Gross profit was $10.4 million and $20.2 million in the second quarter and first six months 2020, respectively compared to $9.7 million and $18.4 million in the comparable 2019 periods, increases of $0.6 million and $1.8 million, or 6.5% and 9.8%, respectively. Gross profit from our lime and limestone operations in the second quarter and first six months 2020 was $10.5 million and $20.5 million, respectively, compared to $9.7 million and $18.4 million in the comparable 2019 periods, increases of $0.8 million, or 8.4%, and $2.2 million, or 11.8%, respectively. The increases in gross profit in the 2020 periods, compared to the comparable 2019 periods, resulted primarily from 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 the decreased revenues discussed above and increased costs incurred in the second quarter 2020 associated with responding to the COVID-19 pandemic. Gross profit also included the impact of losses from our natural gas interests of $150 thousand and $312 thousand in the second quarter and first six months 2020, respectively, compared to profits of $37 thousand and $44 thousand in the comparable 2019 periods.

Selling, general and administrative expenses (“SG&A”) were $2.9 million and $6.1 million in the second quarter and first six months 2020, respectively, compared to $2.6 million and $5.3 million in the comparable 2019 periods. As a percentage of revenues, SG&A was 7.7% and 8.0% in the second quarter and first six months 2020, respectively, compared to 6.8% and 6.9% in the comparable 2019 periods. The increases in SG&A resulted primarily from increased

17

personnel expenses, including stock-based compensation, increased legal expenses, including acquisition-related legal fees, and increased COVID-19 pandemic costs incurred in the second quarter 2020.

Interest expense was $62 thousand and $124 thousand in the second quarter and first six months 2020, respectively, compared to $60 thousand and $122 thousand in the comparable 2019 periods. We had no outstanding debt during any of the periods. Interest and other income, net was $0.1 million and $0.4 in the second quarter and first six months 2020, respectively, compared to $0.5 million and $1.0 million in the comparable 2019 periods, decreases of $0.4 million and $0.6 million, or 78.8% and 64.3%, 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 $1.4 million and $2.7 million in the second quarter and first six months 2020, respectively, compared to $1.5 million and $2.8 million in the comparable 2019 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 $6.1 million ($1.08 per share diluted) in the second quarter 2020, compared to net income of $6.0 million ($1.07 per share diluted) in the first quarter 2019, an increase of $0.1 million, or 1.1%. Net income in the first six months 2020 was $11.6 million ($2.07 per share diluted), an increase of $0.5 million, or 4.3%, compared to net income of $11.2 million ($1.99 per share diluted) in the first six months 2019.

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, 2020. 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

18

below, which is an update to the risk factor included in Part II, Item 1A of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020. Please refer to that section of our Form 10-K for disclosures regarding what we believe are the more significant risks and uncertainties related to our business.

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 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. While many of these restrictions began to be lifted in the second quarter 2020, the easing of restrictions has subsequently been halted or reversed in many our market areas. The pandemic and related restrictions on business activities have resulted in a general economic slowdown, which is has impacted certain industries that purchase our products, including environmental, oil and gas drilling, and steel. 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; 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.  In the second quarter 2020, pursuant to these provisions, we repurchased 2,459 shares at a price of $84.44 per share, the fair market value of one share of our common stock on the date that 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 June 30, 2020 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.
