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, 2018. The results of operations for the three- and six-month periods ended June 30, 2019 are not necessarily indicative of operating results for the full year.

2. Organization

The Company is headquartered in Dallas, Texas, and operates through two business segments. Through its Lime and Limestone Operations, 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 operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, 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 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-operating working interests in natural gas wells located in Johnson County, Texas, in the Barnett Shale Formation.

3. Accounting Policies

Revenue Recognition. The Company recognizes revenue for its Lime and Limestone Operations in accordance with the terms of its purchase orders, contracts or purchase agreements, which is generally upon shipment, and when payment is considered probable. 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 2019 and 2018 revenues was $7.1 million and $6.8 million, for the respective three-month periods, and $13.9 and $12.7 million, for the respective six-month periods, 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. Revenues from the Company’s Natural Gas Interests are from the Company’s royalty and non-operating working interest in Johnson County, Texas. 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.

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. 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 doubtful accounts to reflect estimated losses resulting from the failure of customers to make required payments.

Successful-Efforts Method Used for Natural Gas Interests. The Company uses the successful-efforts method to account for oil and gas exploration and development expenditures. Under this method, drilling, completion and workover costs for successful exploratory wells and all development well costs are capitalized and depleted using the units-of-production method. Costs to drill exploratory wells that do not find proved reserves are expensed.

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 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 9 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. See Note 6 to the condensed consolidated financial statements. There were no changes in the methods and assumptions used in measuring fair value.

The Company’s financial liabilities measured at fair value on a recurring basis at June 30, 2019 and December 31, 2018, respectively, are summarized below (in thousands):


					Significant Other
					Observable Inputs

Foreign exchange hedges	$	(11)	$	(16)	$	(11)	$	(16)	Cash flows approach

New Accounting Pronouncements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (“ASU 2016-02”), “Leases,” which requires the recognition of lease assets and lease liabilities by lessees for all leases greater than one year in duration and classified as operating leases under previous guidance. For operating leases, a lessee is required to recognize at inception a right-of-use asset and a lease liability equal to the net present value of the lease payments, with lease expense recognized over the lease term on a straight-line basis. For leases with a term of twelve months or less, ASU 2016-02 allows a reporting entity to make an accounting policy election to not recognize a right-of-use asset and a lease liability, and to recognize lease expense on a straight-line basis. The Company adopted ASU 2016-02 at January 1, 2019, using the current-period adjustment method. Under the current-period adjustment method, a reporting entity continues to apply legacy guidance, including disclosure requirements, in the comparative periods presented in the year of adoption, recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, if any. Adoption of ASU 2016-02 resulted in an increase in assets of $3.9 million with corresponding liabilities of $3.9 million and no impact on retained earnings at January 1, 2019.

In August 2017, the FASB issued Accounting Standards Update No. 2017-12 (“ASU 2017-12”), “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” This standard better aligns an entity’s risk management activities and financial reporting for hedging relationships and enhances the transparency and understandability of hedge results through improved disclosures. The Company adopted ASU 2017-12 at January 1, 2019. Adoption of ASU 2017-12 had no impact on the Company’s condensed consolidated financial statements.

4. Business Segments

The Company has identified two business segments based on the distinctness of their activities and products: Lime and Limestone Operations and Natural Gas Interests. All operations are in the United States. In evaluating the operating results of the Company’s segments, management primarily reviews revenues and gross profit. The Company does not allocate corporate overhead, interest expense or interest income to its business segments.

The following table sets forth operating results and certain other financial data for the Company’s two business segments (in thousands):

5. Income Per Share of Common Stock

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


	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Net income for basic and diluted income per common share	$	6,033	$	6,638	$	11,161	$	10,900
Weighted-average shares for basic income per common share		5,614		5,595		5,612		5,593
Effect of dilutive securities:
Employee and director stock options(1)		10		8		7		8
Adjusted weighted-average shares and assumed exercises for diluted income per common share		5,624		5,603		5,619		5,601
Basic net income per common share	$	1.07	$	1.19	$	1.99	$	1.95
Diluted net income per common share	$	1.07	$	1.18	$	1.99	$	1.95

⁽¹⁾

Excludes 0 and 14 stock options for the three- and six-month 2019 periods and 2 and 10 stock options for the three- and six-month 2018 periods, respectively, as anti-dilutive because the exercise price exceeded the average per share market price for the period.

In November 2016, 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 for 5.5 million Euros in connection with a contractual obligation related to the St. Clair kiln project, of which FX hedges with respect to 0.4 million Euros remained outstanding at June 30, 2019. In May 2018, the Company entered into additional FX hedges with Wells Fargo to fix the exchange rate for 2.2 million Euros in connection with a contractual obligation related to the purchase and installation of equipment at Arkansas Lime Company, of which FX hedges with respect to 0.3 million Euros remained outstanding at June 30, 2019. At June 30, 2019 and December 31, 2018, the Company had total FX hedges fixing the exchange rates for 0.7 million Euros and 1.4 million Euros, respectively. The Company will be exposed to credit losses in the event of non-performance by the counterparty to the FX hedges. The FX hedges have been effective as defined under applicable accounting rules. Therefore, changes in the fair value of the FX hedges are 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 $11 and $16 at June 30, 2019 and December 31, 2018, respectively, which is included in accrued expenses.

8. Banking Facilities and Debt

The Company’s credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 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 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, 2019, the Company had no debt outstanding and no draws on the Revolving Facility other than $1.2 million of letters of credit, including $0.8 million related to the St. Clair kiln project, which count as draws against the available commitment under the Revolving Facility.

9. Leases

The Company has operating leases for the use of equipment, corporate office space, and some of its terminal and distribution facilities. The leases have remaining lease terms of 0 to 8 years, with a weighted-average remaining lease term of 3 years at June 30, 2019. Some operating leases include options to extend the leases for up to 5 years. At January 1, 2019, upon implementation of ASU 2016-02, the liability for the Company’s operating leases was discounted to present value using a weighted-average discount rate of 3.5%. The components of lease costs for the three- and six-months ended June 30, 2019 were as follows (in thousands):


		Three Months Ended June 30,		Six Months Ended June 30,
	Classification	2019		2019
Operating lease costs (1)	Cost of revenues	$	555	$	1,040
Operating lease costs	Selling, general and administrative expenses		54		107
Rental revenues	Other (income) expense		(13)		(25)
Net lease cost		$	596	$	1,122

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

As of June 30, 2019, 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):

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


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

10. Income Taxes

The Company has estimated that its effective income tax rate for 2019 will be 20.1%. 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. In 2018, the effective income tax rate was further reduced from the federal statutory rate due to research and development tax credits associated with the construction of the St. Clair kiln project.

11. Dividends

On June 14, 2019, the Company paid $0.8 million in cash dividends, based on a dividend of $0.135 (13.5 cents) per share of its common stock, to shareholders of record at the close of business on May 24, 2019. On March 15, 2019, the Company paid $0.8 million in cash dividends, based on a dividend of $0.135 (13.5 cents) per share on its common stock, to shareholders of record at the close of business on February 22, 2019.

12. Subsequent Event

On July 31, 2019, the Company’s Board of Directors declared a regular quarterly cash dividend of $0.135 (13.5 cents) per share on the Company’s common stock. This dividend is payable on September 13, 2019 to shareholders of record at the close of business on August 23, 2019.

Overview.

We currently have two operating segments: Lime and Limestone Operations and Natural Gas Interests. Revenues and gross profit are the primary items utilized to evaluate the operating results of our segments and to allocate resources.

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), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), metals (including steel producers), roof shingle manufacturers, oil and gas services 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 and U.S. Lime Company – Transportation. The Lime and Limestone Operations represent our principal business.

Our Natural Gas Interests are held in our wholly owned subsidiary, U.S. Lime Company – O & G, LLC, and consist of royalty and non-operating working interests under the O & G Lease with affiliated companies of Enervest, Ltd. and the Drillsite Agreement with XTO Energy, Inc. related to our Johnson County, Texas property, located in the Barnett Shale Formation, on which Texas Lime Company conducts its lime and limestone operations. No new wells have been drilled or completed on the O & G Properties since 2011. We cannot predict if any additional wells will be drilled on the O & G Properties, or their results.

Revenues from our Lime and Limestone Operations were essentially flat in the second quarter and increased 3.8% in the first six months 2019, compared to last year’s comparable periods. In the second quarter 2019, sales volumes of our lime and limestone products decreased 1.8%, primarily because of decreased demand, principally from our construction customers, partially offset by increased demand from our environmental customers, compared to the second quarter 2018. In the first six months 2019, sales volumes for our lime and limestone products increased 2.3%, primarily because of increased demand from our environmental and steel customers, partially offset by decreased demand from our construction customers. Weather conditions, particularly in North Texas, interrupted construction projects during the second quarter 2019, which negatively impacted demand for our products in the second quarter 2019. Average prices realized for our lime and limestone products increased 1.8% and 1.5% for the second quarter and first six months 2019, respectively.

Gross profit from Lime and Limestone Operations increased 3.9% in the second quarter 2019 and 14.0% in the first six months 2019, compared to last year’s comparable periods. The increased gross profit from our Lime and Limestone Operations in the second quarter 2019, compared to the second quarter 2018, resulted primarily from increased average prices realized for our lime and limestone products, partially offset by decreased demand. The increased gross profit from our Lime and Limestone Operations in the first six months 2019, compared to the first six months 2018, resulted primarily from the increased revenues discussed above and decreased stripping costs that were more in line with historical patterns, compared to the first six months 2018.

Revenues from our Natural Gas Interests decreased 45.5% and 43.8% in the second quarter and first six months 2019, respectively, compared to the comparable 2018 periods, resulting primarily from lower prices and decreased production volumes due to the normal declines in production rates on our 39 existing natural gas wells. Gross profit from our Natural Gas Interests decreased 88.1% and 92.1% in the second quarter and first six months 2019, respectively, compared to the second quarter and first six months 2018, primarily due to the decreased revenues discussed above.

In the second quarter 2019, our new vertical kiln at St. Clair began producing commercially saleable quicklime. The new kiln is part of a modernization project, which we estimate will cost a total of approximately $50 million. Through the end of the second quarter of 2019, we had incurred approximately $43.3 million on the project, of which $42.5 million had been paid in cash. By the end of the second quarter 2019, we had placed approximately 70% of the total modernization project into service and began depreciating the cost of the assets placed into service. We expect the remaining portion of the project will be completed in the second half 2019.

In December 2015, we commenced a publicly announced share repurchase program to purchase up to $10 million of our common stock. In November 2018, we announced a 12-month extension of the repurchase program through November 2019 to repurchase up to the $7.2 million of our common stock remaining under the program. No shares have been repurchased under the program since the first quarter 2016.

We paid a regular quarterly cash dividend of $0.135 (13.5 cents) per share on our common stock in the first two quarters 2019. On July 31, 2019, the Board of Directors declared a regular quarterly cash dividend of $0.135 (13.5 cents) per share on our common stock. This dividend is payable on September 13, 2019 to shareholders of record at the close of business on August 23, 2019.

Liquidity and Capital Resources.

Net cash provided by operating activities was $20.0 million in the first six months 2019, compared to $18.2 million in the comparable 2018 period, an increase of $1.8 million, or 9.9%. Our net cash provided by operating activities is composed of net income, depreciation, depletion and amortization (“DD&A”), other non‑cash items included in net income and changes in working capital. 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. In the first six months 2018, net cash provided by operating activities was principally composed of $10.9 million net income, $8.6 million DD&A, $1.2 million deferred income taxes $0.7 million stock‑based compensation and a $3.5 million decrease from changes in operating assets and liabilities. Changes in operating assets and liabilities in the first six months 2018 included an increase of $4.5 million in trade receivables, net, a decrease of $1.3 million in inventories, net, and a decrease of $0.7 million in accounts payable and accrued expenses.

We had $12.4 million in capital expenditures in the first six months 2019, including $3.8 million on the St. Clair kiln project, compared to $19.4 million in the first six months 2018, including $11.1 million on the St. Clair kiln project. As of June 30, 2019, we had incurred a total of $43.3 million on the St. Clair kiln project, of which $42.5 million had been paid in cash. We anticipate that most of the balance of the approximately $50 million total cost of the project will be incurred and paid by the end of 2019.

Net cash used in financing activities was $1.7 million in each of the first six months 2019 and 2018, consisting primarily of cash dividends paid in each period.

Cash and cash equivalents increased $6.5 million to $73.7 million at June 30, 2019, from $67.2 million at December 31, 2018.

Our credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 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-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.

We are not contractually committed to any planned capital expenditures until actual orders are placed for equipment. As of June 30, 2019, we did not have any material commitments for open purchase orders.

At June 30, 2019, we had no debt outstanding and no draws on the Revolving Facility other than $1.2 million of letters of credit, including $0.8 million related to the St. Clair kiln project, 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 such as the modernization project at St. Clair, and liquidity needs and allow us to repurchase up to $7.2 million of our common stock remaining to be repurchased under our extended share repurchase program as well as pay regular cash dividends for the near future.

Results of Operations.

Revenues in the second quarter 2019 were $39.0 million, compared to $39.2 million in the second quarter 2018, a decrease of $0.3 million, or 0.7%. Revenues from our Lime and Limestone Operations in the second quarter 2019 and 2018 were $38.6 million in each period, while revenues from our Natural Gas Interests decreased $312 thousand, or 45.5%, to $373 thousand in the second quarter 2019 from $685 thousand in the second quarter 2018. In the first six months 2019, revenues were $76.8 million, compared to $74.5 million in the comparable 2018 period, an increase of $2.2 million, or 3.0%. Revenues from the Company’s Lime and Limestone Operations in the first six months 2019 increased $2.8 million, or 3.8%, to $76.0 million from $73.3 million in the comparable 2018 period, and revenues from our Natural Gas Interests decreased $0.6 million, or 43.8%, to $0.7 million from $1.3 million in the comparable prior year period.

As discussed above, revenues from our Lime and Limestone Operations in the second quarter 2019 were essentially flat, compared to the second quarter 2018, due to the decrease in sales volumes during the second quarter 2019, primarily because of decreased demand, principally from our construction customers, offset by an increase in average prices realized for our lime and limestone products. The increase in lime and limestone revenues in the first six months 2019, compared to the first six months 2018, resulted primarily from increased sales volumes and an increase in average prices realized for our lime and limestone products.

Production volumes from our Natural Gas Interests in the second quarter 2019 totaled 113 thousand MCF, sold at an average price of $3.29 per MCF, compared to 126 thousand MCF, sold at an average price of $5.42 per MCF, in the second quarter 2018. Production volumes in the first six months 2019 from Natural Gas Interests totaled 231 thousand MCF, sold at an average price of $3.06 per MCF, compared to the first six months 2018 when 256 thousand MCF was produced and sold at an average price of $4.91 per MCF. Our average prices per MCF in the second quarter and first six months 2019 were lower than average prices for the comparable 2018 periods primarily due to decreases in market prices for natural gas and natural gas liquids.

Gross profit was $9.7 million in the second quarter 2019, compared to $9.6 million in the second quarter 2018, an increase of $0.1 million, or 0.9%. Gross profit was $18.4 million in the first six months 2019, compared to $16.7 million in the comparable 2018 period, an increase of $1.7 million, or 10.5%.

Gross profit from our Lime and Limestone Operations in the second quarter 2019 was $9.7 million, an increase of $0.4 million, or 3.9%, from $9.3 million in the second quarter 2018. The increase in gross profit in the second quarter 2019, compared to the second quarter 2018, resulted primarily from the increase in average prices discussed above, partially offset by decreased demand. Gross profit from our Lime and Limestone Operations in the first six months 2019 was $18.4 million, an increase of $2.3 million, or 14.0%, from $16.1 million in the comparable 2018 period. The increase in gross profit and gross profit margin in the first six months 2019, compared to the first six months 2018, resulted primarily from the increases in revenues as discussed above, as well as decreased stripping costs that were more in line with historical patterns, compared to the first six months 2018.

Gross profit from our Natural Gas Interests decreased to $37 thousand and $44 thousand in the second quarter and first six months 2019, respectively, from $310 thousand and $554 thousand in the second quarter and first six months 2018, respectively, decreases of $273 thousand, or 88.1%, and $510 thousand, or 92.1%, respectively. The

decreases in gross profit from our Natural Gas Interests in the 2019 periods resulted from the decreases in revenues discussed above.

Selling, general and administrative expenses (“SG&A”) were $2.6 million and $5.3 million in the second quarter and first six months 2019, respectively, compared to $2.6 million and $5.1 million in the comparable 2018 periods, respectively. As a percentage of revenues, SG&A was 6.8% and 6.9% in the second quarter and first six months 2019, respectively, compared to 6.5% and 6.8% in the second quarter and first six months 2018, respectively.

Interest expense was $60 thousand and $122 thousand in the second quarter and first six months 2019, respectively, compared to $63 thousand and $125 thousand in the comparable 2018 periods. We had no outstanding debt during either period. Interest and other income, net was $0.5 million income in each of the second quarters 2019 and 2018. For the first six months 2019, interest and other income, net increased $0.2 million to $1.0 million from $0.8 million, compared to the comparable 2018 period.

Income tax expense increased to $1.5 million in the second quarter 2019, compared to $0.8 million in the first quarter 2018, an increase of $0.7 million, or 78.9%. Income tax expense increased to $2.8 million in the first six months 2019, compared to $1.4 million in the first six months 2018, an increase of $1.4 million or 101.2%. The increases in income tax expense in the second quarter and first six months 2019 was due to research and development tax credits in the second quarter and first six months 2018 associated with the construction of the St. Clair kiln project. Our effective income tax rate for each of the 2019 and 2018 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. Our effective income tax rate for the 2018 periods was further reduced from the federal rate due to research and development tax credits discussed above.

Our net income was $6.0 million ($1.07 per share diluted) in the second quarter 2019, compared to net income of $6.6 million ($1.18 per share diluted) in the second quarter 2018, a decrease of $0.6 million, or 9.1%. Net income in the first six months 2019 was $11.2 million ($1.99 per share diluted), an increase of $0.3 million, or 2.4%, compared to net income of $10.9 million ($1.95 per share diluted) in the first six months 2018.

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, 2019. Any future borrowings under the Revolving Facility would be subject to interest rate risk. See Note 8 of Notes to Condensed Consolidated Financial Statements.

Foreign Exchange Risk.

At June 30, 2019, we had contracts related to the purchase and installation of equipment that require future payments totaling 0.7 million Euros. We have entered into foreign exchange hedges fixing our U.S. Dollar liability at $0.8 million. We could be exposed to changes in the Euro to U.S. Dollar exchange rates for obligations not effectively fixed by the hedges. 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 2: UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In December 2015, we commenced a publicly announced share repurchase program to repurchase up to $10 million of our common stock. In November 2018, we announced a 12-month extension of the repurchase program through November 2019 to repurchase up to the $7.2 million of our common stock remaining under the program. We did not repurchase any shares pursuant to this program in the second quarter 2019.

In addition, 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 2019, pursuant to these provisions, we repurchased 2,361 shares at a price of $80.00 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, 2019 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.
